Okay, so we're asked to draw the lewis -phezzanine instructions for n02 minus.
00:08
Well, n has five valence electrons, and o has six times two since it's two atoms.
00:16
We're going to subtract or add one electrons since we have a minus charge, which gives it a total of 12, 13, 14, 16, 6, and 17, 18 valence electrons.
00:26
So let's draw it out.
00:27
We're going to have nitrogen in the center.
00:29
And let's see.
00:31
So nitrogen has five valence electrons.
00:35
So if there are one, two, three, four, five.
00:40
Okay.
00:40
And oxygen has, let's draw out an oxygen right here.
00:44
It has six.
00:45
So one, two, three, four, five.
00:49
If you do that incorrectly.
00:52
Three, four, five, six...
