Hi there.
00:04
In this question, we are working with arsenic.
00:07
And we see that arsenic is located right here on the periodic table.
00:11
It is in group 5a.
00:14
And since it is in group 5a, that means it has five valence electrons.
00:21
So if we look at arsenic as a dot structure, it will have five valence electrons.
00:31
And arsenic is a non -metal.
00:34
Technically, it's a metalloid, but it falls on the non -metal.
00:37
Side of the line that separates metals from non -metals.
00:41
So we can classify it as a non -metal, which means when it forms an ion, it is going to gain electrons.
00:50
It wants to satisfy the octet rule.
00:53
So it could lose all five of these electrons, or it could gain three.
00:59
By gaining three electrons, it would have an octet.
01:03
So that's what it's going to do...
