Across
- 2. a group of covalently bonded atoms that together have gained or lost electrons
- 4. attraction of metal atoms and their sea of shared electrons
- 6. atoms are more stable when all eight electrons in their valence energy level are full
- 7. chemical formula for an ionic substance
- 9. the opposite electrical charges on these ions attract each other
- 11. molecules made of two atoms whether of the same element or not
- 13. similar way to model a covalent bond
Down
- 1. made from only two elements
- 3. shows the electric charge gained or lost by that element when it forms a compound
- 5. shortened way of identifying a chemical compound
- 8. unequal distribution of electric charge
- 10. a chemical bond formed as a result of two atoms sharing electrons
- 12. an electrostatic attraction that forms between atoms when they share or transfer valence electrons
