To draw the m -o diagram for c2, 2 plus, we first need to know the order of the molecular orbitals.
00:11
So we'll start out with sigma 1s, sigma 1 -s star, and then we'll go to sigma 2s and sigma 2s star.
00:27
And then for carbon, we have the pi 2ps before the sigma 2p.
00:45
So pi 2p, then we have sigma 2p, and then we have pi 2p, and then we have pi 2p star, and sigma 2 .p star.

The total number of valence electrons is going to be, well, the total number of electrons because they want all the core electrons, including the valence.
01:14
Carbon has six electrons.
01:18
There are two of them, plus two are taken away, so minus two because of the two plus charge, giving us a total of ten electrons.
01:31
So we plug in those ten electrons...
