The Chemical Basis for Life. Importance & Properties of Water Molecular Shape and Properties A water molecule is composed of two hydrogen atoms and one.
By Chris Paine 2.2 Water Essential idea: Water is the medium of life. The cohesive nature of nature gives it surface tension.
Water. Covers more than 75% of the Earth’s surface, and makes up 70-95% of most organisms.

Example: Find the electric field at point P Rework of this example (21.6 in book)
Properties of Water: Polarity The oxygen and hydrogen atoms in water share electrons unequally (a polar covalent bond). This happens because the oxygen.

Example: Find the electric field at point P
Water and Polarity Chapter 2. What is electronegativity? The tendency of atoms to attract electrons to itself in a chemical bond – electronegativity.
