How can I draw the Lewis structure for PH3?
February 20th, 2023
Phosphosus has an of ##[Ne] 2s^2 2p^3##.
Therefore, it has a dot digram in the red of two electrons on top and one electron on each side. Providing for three open sites.
Hydrogen has an electron configuration of ##1s^1##. Therefore, it has only one electron on top. Each of the three hydrogens will fill one of the empty spaces of the phosphorus atom in a covalent bond. This will provide eight electrons for phosphorus, to complete the rule of octet.
Each hydrogen now has two electrons to complete the rule of duet.
I hope this was helpful.
