Cations and Anions

Cations are ions with a POSITIVE charge. Anions are ions with a NEGATIVE charge. Draw the funny way to remember cations

and anions:

Compounds

Atoms bonded together with an IONIC bond are called compounds.

An ionic bond is a METAL bonded with a NONMETAL.

Draw the crystal lattice structure for sodium chloride:

 Empirical Formula

Refers to the ratio of ions in a compound

NaCl has a ratio of 1:1 (1 to 1). MgCl2 has a ratio of 1:2 (1 to 2). AlCl3 has a ratio of 1:3 (1 to 3).

Oxidation Number

Charge that an atom will have if made into an ion.

Na becomes Na+, so its oxidation number is POSITIVE.

Cl becomes Cl-, so its oxidation number is NEGATIVE.
