It has one lone pair left.
None.
Basically the nonmetals. Many of them receive electrons, like oxygen, nitrogen, selenium, tellurium, and many others.

49 protons, 64 neutrons and 49 electrons.
Here are 16 valence electrons: 3 from H, 8 from O and 5 from P.
One lone pair and three bonding chlorine pairs. General shape is tetrahedral and it's a trigonal pyramidal.
Four pairs of electrons. Neon has a full octet.

There is one lone pair of electrons on the nitrogen atom.
If an atom has five valence electrons, it will have one lone pair of electrons.
There are 2 lone pairs in each Oxygen atom. So there are 4 lone pairs in total, which means 8 lone pair electrons.
There are three lone pairs present in chlorine atom
There is one lone pair of electrons on the nitrogen atom.
