3 bonding pairs and one lone pair or non-bonding pair
YES
Phosphorous has a total of 15 electrons, and of those, 3 of them are valence shell, or bonding electrons. So, 12 electrons are core electrons, and are non-bonding.
The optimum number of electrons in the outermost valence shell for phosphorus atoms is eight, known as an octet. Unbonded phosphorus atoms have 5 valence electrons and undergo chemical bonding in order to gain the other 3, either by covalent bonding or by ionic bonding.
