Hey mate here is your answer

Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond. ... That is the ideal electron configuration.

Hope this answer will help you!!

The number of valence electrons is 5 + 3×7 = 26.

If you draw a trial structure in which P is the central atom and every atom has an octet, you will have used 26 electrons.


This is the correct number of electrons, so the trial structure is the correct structure.

The P atom in PF3 has one lone pair of electrons.



if it helps mark as brailleast
