Chemistry 3
Across
- 3. Number assigned to the charge of an ion in building compounds
- 5. When electrons are shared between 2 nonmetals
- 6. a naming system
- 9. Bonded atoms have an unequal attraction for shared electrons; unbalanced charge
- 11. Charged group of covalently bonded atoms
- 12. Electrons are shared equally by bonded atoms; balanced charge
Down
- 1. only valence electrons of an element are placed around the element symbol
- 2. Uses Roman numeral to indicate ion's charge
- 4. readily evaporates into a gas
- 7. When electrons are transferred between a metal and nonmetal
- 8. Delocalized electrons move freely among positively charged ions
- 10. Outermost valence shell needs 8 electrons for stability
