Base any substance that forms hydroxide ions in water and has a pH above 7
Comnpound substance composed of atoms of two or more different elements that are chemically combined
Covalent bond chemical bond formed when two atoms share electrons
Element substance taht cant be broken down into simpler chemical substances
Ion atom or group of atoms that gain or lose electrons
Ionic bond chemical bond formed by the attractive forces between two ions of opposite charge
