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.

INFO

Ok... To the below are the colours of  the atoms in a molecular model...

O H   Hydrogen	White
O       Alkali Metals	Violet
O       Alkaline-Earth Metals	Dark Green
O       Boron, Most Transition Metal	Pink
O C   Carbon	Black
O N   Nitrogen	Dark Blue
O O   Oxygen	Red
O F    Fluorine, Cl   Chlorine	Green
O B    Bromine	Dark Red
O I     Iodine	Dark Violet
O       Noble Gases	Cyan
O P   Phosphorus	Orange
O S   Sulfur	Yellow
O Ti  Titanium	Gray

So yeah...

Now I shall tell you, 3 molecular bonds:

Covalent - When two atoms are sharing an electron and are both tugging at that electron

Ionic - There are two atoms, one positively charged and another negatively and they're tugging on each other

Metallic - The electrons are shared between all atoms making an electron sea and all the atoms positively...
                   I don't really get it... But it's metalic... Basically an everywhere covalent...

A periodic table i got from google images... hmm...

Page introduction...

On this page, I will be writing down some random science thoughts.

I will also be making a "Atom or molecule" of the day, probably not everyday but you get the point. In that I will be putting a few pictures on this page to show what it is and I will list a few facts, because, the facts are always the best part!
