Let"s look to the periodic table because that our answer! The routine table tells us information about every facet in visibility in the neutral state. The neutral state of one atom is once it"s net fee is zero; the is, the variety of protons amounts to the numbers of electrons. Oxygen is the eighth aspect in the routine table, v the price O. This method that it has eight electron in the neutral state. Since it is neutral, it additionally has eight protons!

The routine table has another number associated with every element, and that is it"s atomic mass.

You are watching: Gas with 8 protons and 8 neutrons

for oxygen, the atom mass is 16 AMU (Atomic mass Units). In regards to mass, protons and neutrons have about the same mass, and electrons have actually very little mass in comparison. Protons and also neutrons each count for one AMU, and the electron counts because that zero AMU. So, if the atomic mass the oxygen is 16, that means we have actually a complete of 16 protons and also neutrons. 16 total protons and neutrons minus 8 protons pipeline us through 8 neutrons.

This calculation can gain surprisingly tricky! The atom mass the an element is an mean over all of the isotopes of every element. An isotope is an aspect that has actually a different variety of neutrons in different atoms. The chemistry properties that the facet don"t change, however the atomic mass of the element is different if the has, say, 8 neutrons matches 9 neutrons. Due to the fact that the atom mass the each facet is averaged over every stable isotope of the element, periodically we view decimal numbers because that the atom mass. For example, the atom mass of carbon (the 6th element top top the routine table) is 12.01 AMU. This tells us that most carbon atoms have actually 6 protons and also 6 neutrons, and some carbon atoms have actually 6 protons and maybe 7 or 8 neutrons.

Most carbon atoms have 6 protons and also 6 neutrons, so the atomic mass is an extremely close come 12 AMU. Researchers have uncovered the family member abundance of each element and isotope, so we canlook up how typical an isotope is. For oxygen, the isotope through 8 protons and 8 neutrons makes up 99.7% of all oxygen atoms, therefore its a for sure bet to say that oxygen virtually always has 8 protons and 8 neutrons.

Answer 2:

I"ll start by answering the question directly: in general, element oxygen has 8 protons, 8 neutrons, and 8 electrons. Your concern is an exciting one, since it is frequently the beginning point for many other questions we can ask around elements, chemicals, and also materials.

For instance, despite we frequently refer come the gas us breathe as just "oxygen", that is actually the molecule O2 (two oxygen atom bonded together).

The reason for this needs to do v the variety of electrons oxygen has. Electrons have a certain method of arranging us on atoms, and also we have the right to think the electrons together existing in "shells" about the atom"s nucleus. For now we deserve to think of atom as having actually "inner" and also "outer" shells. Oxygen has an inner covering that have the right to hold 2 electrons, and an external shell that can hold 8. Shells room filled from the innermost to the outermost, so since oxygen has 8 electrons, we put 2 in the inside shell, and the remaining 6 in the outer shell. together we deserve to see, there"s still two empty spots for electrons to go in the external shell (which can hold 8), and also the oxygen would certainly really favor to fill those spots. The does this in a clever way; it looks because that a partner! If two oxygens obtain together, they have 16 electrons total. By "sharing" 4 of them, lock each gain to "keep" half of the continuing to be electrons (16 full - 4 shared = 12 remaining, 12/2 = 6 each). On each oxygen, 2 of these 6 go in the inside shell, and the various other 4 walk in the outer shell. Now, the oxygens relocate close together, and they re-publishing the 4 remaining electrons the they didn"t "keep". This way they both get to feel choose they have actually a complete outer covering (4 the they have to themselves, 4 that space shared in between them). This is the O2 gas the you and I breathe!

This is simply one instance of the species of things that counting electrons deserve to predict. Often, the variety of electrons in an facet can phone call us about the what shade it can be, even if it is or not it"s a magnet, or what types of other facets it will certainly react with. Also, if you ever want to know how countless protons and electrons an additional element has, it"s as basic as looking in ~ the atomic number ~ above the routine table (the big number in the optimal of the box for every element). That number speak you the number of protons an facet has, and also by extension tells you the number of electrons the has. Elements are charge neutral (meaning the charges include up come 0), and since protons have actually a optimistic charge, each proton is well balanced out through 1 electron, which has actually a negative charge. The case with neutron (which have no charge) deserve to be a little more complicated, yet the number of neutrons is often the very same as or comparable to the variety of protons.

Answer 3:

This is answered pretty totally on piersonforcongress.com here. One refinement is to think about ions, whereas the answers in ~ the connected question considers just neutral oxygen atoms. In general, the power of an atom will be lower, then the valence (outermost) electron covering is full. For virtually all elements, this means gaining or losing electrons to other atoms, thus developing ions.

while the neutral oxygen atom has actually 8 total electrons, 2 are in the innermost (s) shell while the valence shell, which deserve to hold 8 electrons, has only 6. Thus, oxygen tends to obtain 2 electrons, for a total of 10 electrons. This outcomes in an atom v a net charge (i.e., an ion).

Answer 4:

In an oxygen atom, there space 8 protons and 8 electrons. Many oxygen atoms additionally have 8 neutrons, yet it is feasible for an oxygen atom to have 9 or 10 neutrons. Lock are simply rarer. The oxygen us breathe is no in atom form. That is in its molecule form, i m sorry is two oxygen atom joined together by bonds, and between its two atoms, this molecule has actually 16 protons, 16 electrons, and also most commonly 16 neutrons.

Answer 5:

An oxygen atom includes eight protons.

A neutral oxygen atom will additionally contain eight electrons, but it is feasible for one oxygen atom to it is in ionized, in which instance it will certainly have more or fewer (up come ten, or under to zero), depending on how it came to be ionized.

Oxygen has several isotopes, and also they have different numbers of neutrons. The most typical isotope the oxygen is oxygen-16, which has eight neutrons; however, oxygen-18 is also fairly common, and it has ten neutrons. Both of these isotopes space stable (i.e. No radioactive).

Oxygen-17 (nine neutrons) is likewise stable, however is rarer. Having too many neutrons, or also few, will certainly make the oxygen isotope radioactive, however still oxygen.

Answer 6:

Oxygen is #8 in the regular table. That way it has actually 8 protons and 8 electrons. The variety of neutrons varies according come the isotope: the stable isotopes have actually 8, 9, or 10 neutrons(Wikipedia).

Did you understand that this is the global Year of the periodic Table - IYPT? One fun thing people are law is finding the facet that is the exact same number as their age. Next year my period will be the very same number as Tungsten.

Here"s an article about the IYPT from a chemistry magazine ns get: read it here.

Answer 7:

Generally, there space 8 protons, 8 neutrons and also 8 electron in the most abundant oxygen molecule. Here"s where it gets progressed and cool! as soon as Oxygen loses or gains neutrons it becomes an isotope. Oxygen isotopes are hardly ever occurring and have useful applications. Because that example, brain imaging in hospitals provides Oxygen 15, comprise 7 neutrons.

Answer 8:

An oxygen atom usually has actually 8 protons, 8 neutrons, and 8 electrons. Looking in ~ the routine table, oxygen has atomic number 8 and also atomic load 15.999. The atom number tells you how plenty of protons space in the atom"s nucleus. This identify the atom.

for example, if the atomic number to be 7, climate the atom would certainly be nitrogen, through 7 protons in that is nucleus. The atom nucleus contains both protons and also neutrons, but the amazing thing is the there aren"t always an equal variety of neutrons and protons. This information is revealed in the atom weight, i beg your pardon is a number that refers to the mean mass that the cell core (in atom mass systems or amu). If all of the oxygen atoms we recognize about, constantly had 8 protons and 8 neutrons, then the atomic weight would certainly be 16. But we recognize that some develops of oxygen have actually fewer 보다 8 neutrons in their nucleus, and also that is why the atomic load is a tiny bit much less than 16. Oxygen"s 8 electrons space negatively charged, and also they orbit the atom nucleus and also balance the hopeful charge the the 8 protons. The confident charge of 1 proton specifically cancels the negative charge that 1 electron.

Answer 9:

Oxygen is atomic number 8 on the regular table, which means it has actually 8 protons! This method that a neutral oxygen atom will have 8 electron (but this number deserve to change! for example, throughout chemical reactions molecules deserve to lose and also gain electrons). The variety of neutrons counts on the isotope, yet a secure isotope will generally have either 8, 9, or 10 neutrons.

Answer 10:

Thanks for her question, and let’s start with the basics: just how chemical aspects aredefined, particularly on the regular table that elements.

The major, totality numbers above the elements on the routine table of facets (you’veprobably seen one in your scientific research instructor’s room) determine the element and also it describes the variety of protons together a definitional component of the element’s identity. It is the long version of this basic fact: oxygen will always have 8 protons, even if it is on Mars, Pluto, Earth, yesterday, or the work after tomorrow.Next, let’s think about the number of neutrons and electrons in oxygen: in short, they’rechangeable within natural constraints. In the case of neutrons, oxygen has different isotopes, i m sorry are various versions the oxygen that preserve their number of protons, but readjust their variety of neutrons. In our clinical observations, oxygen has actually either 8, 9, or 10 neutrons.

Now, in regards to electrons, oxygen should contain 8 electrons in stimulate to be isoelectric, which is a way of saying the electrons equal the number of protons, rendering no charge to the oxygen atom, and also this is thought about the most herbal state of the oxygen atom (you deserve to “add”/”subtract”electrons by high energy collisions with fragment accelerators, however that’s an ext artificial, anddepending top top the reference point, oxygen deserve to “gain” electrons throughout molecular bonding).
