beginning of the name The name is derived from the Greek "phosphoros", meaning bringer of light.
Allotropes White P, Red P, black P, P2


GroupA vertical pillar in the periodic table. Members the a group typically have comparable properties and electron configuration in their external shell.

PeriodA horizontal heat in the routine table. The atomic variety of each facet increases by one, reading from left to right.

BlockElements are organised right into blocks by the orbital type in i m sorry the external electrons are found. These blocks are named for the properties spectra lock produce: spicy (s), major (p), diffusive (d), and fundamental (f).

Atomic numberThe number of protons in an atom.

Electron configurationThe species of electrons above the critical (closed shell) noble gas.

Melting pointThe temperature at which the solid liquid phase change occurs.

Boiling point The temperature at which the lpg phase change occurs.

SublimationThe change of a substance straight from the solid come the gas step without passing through a liquid phase.

Density (g cm−3)Density is the massive of a problem that would certainly fill 1 cm3 in ~ room temperature.

Relative atomic massThe fixed of an atom loved one to the of carbon-12. This is around the sum of the variety of protons and also neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.

IsotopesAtoms of the same aspect with various numbers the neutrons.
