Down
- 1. Electrons are not shared equally
- 3. Formed when atoms gain 1 or more valence electrons
- 4. The lowest whole number ratios of ions in an ionic compound
- 7. Three shared pairs of electrons
- 8. States the repulsion between electron pairs causes molecular shapes to adjust so that valence electron pairs stay as far as possible
- 9. Two shared pairs of electrons
- 11. Attractions between molecules, they are much weaker than either covalent or ionic bonds

- 13. Neutral groups of atoms held together by covalent bonds
- 14. Molecules that contain two atoms of the same element
- 17. Shows how many atoms of each element a molecular compound contains
- 19. Composed of a cation and anion, they are electrically neutral
