| IONIC BOND | The attraction between the positive metal ions and the negative non-metal ions causes a bond (ionic bond) to be formed. |
| ELECTRONEGATIVITY | Tendency of an atom to attract electrons |
| PERIODIC TABLE | Metals: Left of zigzag Nonmetals: Right of zigzag Metalloids: On zigzag |
| VALENCE ELECTRONS | Number of electrons in last (outer) shell of electron configuration |
| ION | A charged atom or molecule, can be negative (electron ANION), positive (proton CATION), or neutral (nueron) |
| CHEMICAL BONDS | Bond is formed= Exothermic Bond is broken= Endothermic |
| COVALENT BONDS | form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms |
| MOLECULE | A group of atoms bonded together |
