Water Molecule - H2O

Ok, I'm going to start with talking about... A water molecule...

I must admit it's pretty obvious what the molecular formular is, "H2O", basically an oxygen with two hydrogen atoms covalently atached... You should probably think of all the elements with a low atomic number a lot smaller than one with a high, they can get really big... Compared to other atoms...

Anyway, a water molecule has a Oxygen atom which wants more electrons than eight and shares one from each hydrogen. I think the  Oxygen wants more than eight because it's pretty far to the right on periodic table and hydrogen is on the very left. So basically the furthur to the right is the more it wants to take electrons and the furthur to the left is it wants to give.                   By the way, the angle between the two Hydrogens are 104.45° (on the top).

I made those two lines to the atoms which are bit out of the screen in my picture to show how the molecule are bonded to the next... I think that the hydrogens from the other molecules are moving towards the oxygen, because the hydrogens are negatively charged (Cation) and oxygen positively (Anion).

A water molecule has a "polar covalent" bond, which means the hydrogens are on either side of the Oxygen...   I believe it's like that because of how the hydrogens are positievely charged and want to keep away from each other. Although, I don't really know why there would be an exact angle between the the two hydrogens... 

Hmm... Maybe because of the the other hydrogens in other water molecules... Hmm.
