Subscript in the chemistry formula suggest the variety of atoms the the aspect immediately before the subscript.

You are watching: In the compound mgcl2, the subscript 2 indicates that

In MgCl₂ there space two(2) atom of chlorine since Subscript 2 is immediately after chlorine.

Answer : The correct choice is D.

Explanation :

The offered compound is .

When is dissolve in water then they dissociates right into two ions such together magnesium ion and chloride ion.

It is represented as,


The fee on magnesium ion is +2 and on chloride ion is -1. To neutralize the fee on magnesium ion, two chloride ions must be used.

In , the subscript 2 shows that


Further Explanation:

The attraction in between atoms, molecule or ions which outcomes in the formation of chemical compounds is known as a chemistry bond. The is created either due to electrostatic forces or by the share of electrons. There room many strong bonds such as ionic bonds, covalent bonds, and metallic bond while part weak bonds prefer dipole-dipole interactions, London dispersion forces, and also hydrogen bonding.

Ionic compounds space the compounds the are created from the ions of the respective species. Ions are the species that are formed either due to loss or acquire of electrons. A neutral atom creates cation by the loss of electrons and also anion by the get of electrons.

There is development of ionic bond in situation of . Magnesium, gift a steel loses 2 electrons and is formed. These electrons are embraced by 2 chlorine atoms and two ions are formed.

The dissociation of occurs as follows:

Here, one and also two are formed. This suggests that there space two chlorine ions for every magnesium ion. So the subscript in the chemistry formula the shows the existence of 2 chlorine atoms every ion that magnesium. This indicates statement A is incorrect and also statement D is correct.

The chemistry formula that the compound has actually nothing to perform with the size of the ion formed during the link formation. For this reason subscript offers no idea around the dimension of the ions. This suggests statement B is incorrect.

A covalent bond requires shared sharing the electrons in between the external inspection atoms. Yet there is one ionic link formation between magnesium and chlorine due to difference in their electronegativities. So a twin covalent bond can not be formed between chlorine and also magnesium. This suggests statement C is incorrect.

The exactly answer is answer selection D, there are two chloride ions for every magnesium ions. Subscripts always indicate the number of atoms, or ions, existing in the molecule. The 2 refers to the facet directly to its left, so answer choice A is reversed; there room 2 chloride ions for every magnesium ion, not the other means around. Answer choice B and C room incorrect due to the fact that the subscript describes the variety of atoms, not the size of the atom or the type of bond.
