How many unpaired electrons are in each of the following? for a, we have oxygen, which has eight electrons.
00:07
Let's draw its electronic configuration.
00:10
We've got 1s, 2s, 2ps, as far as we need to go.
00:16
And we've got 1, 2, 3, 4, 5, 6, 7, 8.
00:23
Here we can see we have 2 unpared electrons.
00:28
For b, we've got silicon.
00:34
Silicon has 14 electrons drawing its electron configuration.
00:39
1s, 2 s, 2p, 3s, 3p, placing 14 electrons, 1, 2, 7 ,000, 1, 2, 3, 4, 6, 7, 8, now 10.
