H20 is a water molecule that is made up of two hydrogen atoms and one oxygen molecule. Water has a very unique atom structure. The partial positive charge from the hydrogen and negative charge result in a strong bond between the atoms. This also leads to a high boiling point and density. This is one of the most simple yet vital things in life. Every living thing needs this compound to survive. We interact with it every single day. Water is a very neutral substance as it used to clean and water down strong substances. So every time you wash your hands or take a sip of water just remember that is a simple but yet the most important molecule that we interact with everyday.
