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