TermDefinition
Octet rule atoms want to get the magic number of 8 valence electrons
ionic bond weak, lose or gain electrons, can easily be pulled apart
positive and negative charges are attracted to each other
covalent bond share electrons, strong
ionic bond example drawn with dots as electrons
covalent bond example drawn with lines and letters
Non-polar electrons are shared evenly
polar electrons are shared unevenly
intermolecular force force that holds molecules together
cohesion water molecules stick together
adhesion water sticks to things like water
hydrophilic water loving, polar molecules, will mix with water
hydrophobic water fearing, will not mix with water, nonpolar
capillary action water is attracted to things with a negative charge
