Here's the breakdown for question 8: A molecule is a group of two or more atoms held together by chemical bonds, and it is electrically neutral. A radical (or polyatomic ion) is a group of atoms covalently bonded together that carries an overall electrical charge. HSO_4^-: This is a group of atoms with an overall negative charge. It is a radical*. Cl_2: This consists of two chlorine atoms bonded together and is electrically neutral. It is a molecule*. OH^-: This is a group of atoms with an overall negative charge. It is a radical*. H_2: This consists of two hydrogen atoms bonded together and is electrically neutral. It is a molecule*. CO_3^2-: This is a group of atoms with an overall negative charge. It is a radical*. Therefore: Molecules: Cl_2, H_2 Radicals: HSO_4^-, OH^-, CO_3^2- That's 2 down. 3 left today — send the next one.
