Chemical formula for phosphorus

Answer 1

Phosphide itself is not much. I think what you mean is the phosphide ION. The formula for phosphorus is P, as you must know, but the phosphide ion is P3- ( the ionic charge being in superscript)

And it is so because when bonding, Phosphorus will gain three more electrons to complete its full octet as before bonding, it only has 5 electrons in its valence shell.

Answer 2

These compounds are Fe(III)P and Fe3(II)P2.
