Down
- 1. an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
- 2. An atom with more or less electrons than protons
- 5. drawing that shows valence electron movement between atoms
- 6. Number assigned to an element in chemical combination that represents the number of electrons lost
- 8. an electron moves from an atom or a chemical species to another atom or chemical species
- 9. valence of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion's charge.
