Term
ionic bond
Definition
when one atom gives an electron (or more) to another atom. The resulting atoms become tons and are attracted to each other
Term
covalent bond
Definition
when atoms share electrong, allowing the outermost shells of both atoms to be filled; stronger than ionic bonds
Term
hydrogen bond
Definition
attraction between a partially positive and negative other atom
Term
polarity
Definition
when electrons are shared unequally, one atom is partially negative, while the other is partially positive.
Term
cohesion
Definition
water molecules stick to each other with hydrogen bonds
Term
surface tension
Definition
liquid water keeps its shape because the molecules stick to one another
Term
adhesion
Definition
polar water molecules atick to polar water molecules in other substances
Term
capillary action
Definition
the tendency of water to move uo (against gravity) a substance due to adhesion
Term
surfactant
Definition
a chemical that lowers the surface tension of a liquid (works because of hydrophobis and a hydrophilic end)
Term
surfactant
Definition
a chemical that lowers the surface tension of a liquid (works because of hydrophobis and a hydrophilic end)
Term
hydrophobic

water fearing (non-polar, oil)
Term
hydrophilic
Definition
water loving (polar, glass, salt)
Term
monomer
Definition
simple sugar, monosaccharide
