Phosphorus is atmotic number 15 when it comes to bonding with other atoms, what is phosphorus most likely to do?

Phosphorus has an electronic configuration in the simple form 2,8,5 and a spdf configuration of 1s² 2s² 2p⁶ 3s² 3p³.

The valence electrons in phosphorus (the electrons available for bonding) are 5.  As a result, an atom of phosphorus shares its electrons with another atom to form COVALENT bonds.  This is ideal since it would take a high amount of energy to release these five electrons, and it would be unlikely for atoms to lose 5 electrons to donate to phosphorus.

I’m going to go with b!
