•50-75% of our body is water

•Atoms are joined by polar covalent bonds

•Molecule is V-shaped at 105-degrees

•The shape and polarity allows hydrogen bonding to occur

Solvency

(Property of Water)

Adherence

(Property of Water)

The abilty for water to adhere materials

to objects (ex. cells)

•Allows for living things to hold water and materials.

Cohesiveness

(Property of Water)

The ability of water through its motion to collect materials

•Establishes deposits of materials for living things.

Chemical Reactivity

(Property of Water)

Ability to participate in chemical reactions

•Ionizes into chemically reactive H⁺ and OH^-

(aka Stubberness)

(Property of Water)

•4 valence electrons

•Forms four non-polar bonds

•Forms long chains and rings
