Okay, for this question, we are going to be drawing the lewis structure of h2s.
00:17
So we're going to start by counting the number of valence electrons we need.
00:22
So we have two hydrogens, each with one valence electron, plus sulfur is in the group six.
00:30
So this is going to have six valence electrons, which equals a total of eight valence electrons that are open for bonding.
00:40
The shortcut to determine the number of bonds that there will be is to determine the number of total electrons needed to satisfy the octet rules.
00:51
Hydrogen is an exception where it only needs two electrons to satisfy the octet rule, and then we have sulfur needing eight electrons to satisfy its octet rule, which ends up coming out to 12.
01:06
If we subtract the total number of electrons minus the number of electrons.
01:11
Number of valence electrons available, we end up getting four electrons that are going to be shared...
