Question

How many electrons occupy the Px orbitals of Hg

Answer 1

The Px orbital is one of three orbitals in the P subshell.
And, only 2 electrons can occupy an orbital.
So, 2 I suppose.
I hope this isn't a trick question.

Answer 2

Oh, okay, so if there is 4 p orbitals total in the electron configuration of Hg, then it would be 2 x 4, which would be 8?

Answer 3

There are only 3 orbitals in the p subshell, 2 electrons to each orbitals, so 6 electrons can be in the p subshell.
