Front

chemical bond

Back

is the attractive force that holds atoms together in a compound

Front

Ion

Back

is a charged particle that has either fewer electrons than protons (a positively charged cation) or more electrons than protons (a negatively charged anion)

Front

Polar bond

Back

a bond in which electrons. are shared unequally resulting in a slightly positive end and a slightly negative end.

Front

Polar molecule

Back

is one in which the unequal Sharing of electrons result in a slightly positive end and a slightly negative end.
