bond

A force that holds some atoms tightly together.

ion

Atom or group of atoms with an electrical charge. Atoms become positively charged ions if they lose electrons and negatively charged if they gain electrons.

ionic bond

Strong electrostatic force of attraction between oppositely charged ions.

polyatomic ions

A group of atoms that have a positive or negative charge due to the loss or gain of electrons.

compound

Contains atoms of more than one element chemically joined together with an ionic bond.

metals

Any element that is shiny when polished, conducts heat and electricity well, is malleable and flexible and often has a high melting point.

non-metals

Any element that is not shiny, and does not conduct heat and electricity well.
