What is the geometric structure of the water molecule?

How many pairs of valence electrons are there on the oxygen atom in the water molecule? I know oxygen has 6 valence electrons (since it is in group 6 on the periodic table), but would it have 8 (4 pairs) since it is combined with the two hydrogen atoms?

Yes, it will have four pairs, Six come from oxygen and two come from the two H atoms. They are arranged like this and the molecule is angular.
