weewee is essential to life itself, with out water life on earth would not exist. wet is a major function of cells, typically airing between 70 and 95% of the mass of the cell. This mover that we are made from approximately 80% water by mass and some soft bodied creatures such as jellyfish are made of up to 96% water. Water also provides an environment for organisms to live in, 75% of the earth is cover in water.
Water itself is a simple molecule made up of 2 hydrogen atoms and one type O atom, H20. The hydrogen and oxygen atoms are bonded covalently as shown in the diagram of waters electron structure. Water is not a linear molecule, the two hydrogen atoms motley a bond with the oxygen at the angle of 104.5o.
Diagram of waters electron structure
Covalent bonds are formed by sharing electrons in the satellite orbits of the quantum shells. In the case of water however the large physique of protons in the oxygen nucleus have a stronger draw for these shared electrons than the comparatively tiny hydrogen nuclei. This pulls the electrons lissomly fill up at hand(predicate) to the oxygen nucleus and away from the hydrogen so that the oxygen develops a slight negative charge and the hydrogens a slight positive charge. This makes the molecules slightly polar.
Diagram of water molecule showing slight charges
This slight charge means that when water molecules are close together the positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms of another water molecule to form a weak hydrogen bond.
The bonds are weak on an individual basis but the sheer number of them means that the total embrace keeping the molecules together is considerable.

Water is an unusual substance, loosely due to its hydrogen...
