Biology Notes: Water

Water:

Basics:

• Water is composed of one Oxygen atom and two Hydrogen atoms.
• Oxygen is electronegative
• The Hydrogen atoms are bonded to the Oxygen covalently (sharing electrons) 
• A water molecule is polar.
• Polarity= The uneven distribution of electrons, charged.

• The Oxygen atom in a water molecule posseses a slight negative charge.
• The Hydrogen in a water molecule posseses a slight positive charge.
• Hydrogen bonds form between the negative Oxygen of one water molecule and the positive Hydrogen of a different molecule.
• The hydrogen bonds between water molecules are weak and are constantly breaking and reforming.
• Due to the sheer number…
