What is bonding?
2 or more atoms coming together to form a molecule
Does a molecule have to have two different elements?
no, two of the same element can form a molecule
Define:
Ionic bond
electron transferred from one atom to another.
EX: salt (NaCl) (sodium & chloride)
Define:
Covalent bond
electrons shared within a molecule; happens in organic organisms
EX: methane gas - Carbon + 4 Hydrogens
Define:
Hydrogen bond
1 entire molecule has a charge and attracks molecules with the opposite charge, like a magnet
EX: water

Characteristics of Inorganic molecules
typically have no carbon (not always though), not made by living systems
Ex: salt, water, and Carbon Dioxide (CO2)
Characteristics of organic molecules
WILL have carbon (always), are made by living organisms
Why water (H2O) is in living organisms?
* is a universal solvent (will break down anything)
* molecules are cohesive (stick together due to hydrogen bonding)
* temperature of water rises and falls slowly
* H2O tends to remain liqued
