  1. 2. Forms between a metal and nonmetal
  2. 5. Forms between two nonmetals
  3. 7. Form when electrons are gained
  4. 8. A group of atoms bonded together
  5. 9. In molecule model of the atom,each energy level is divided into smaller sublevels or orbitals
  6. 10. equation Is the symbolic representation of a chemical reaction in the form of symbols and formulate where in the reactant entities are given on the left hand side and the product entities on the right hand side
  7. 12. Form when electrons are lost,change is +because there are more protons than electrons
Down
  1. 1. Is an outer shell that is associated with atom
  2. 3. An atom is (stable) when the valence energy level contains a full 8 electrons
  3. 4. The electrons move in definite “orbit”or energy level (n)around the nucleus
  4. 6. The stuff you start with
  5. 11. Are atoms of groups of atom with a change ions are formed when atom or group of atoms other gain of lose electron
