Across
- 3. Solid, hard, high melting & boiling point, conducts heat & electricity well, shiny
- 4. Number of Protons
- 7. Neutral; inside nucleus; Calculate mass-atomic #
- 8. Liquid or gas, low melting & boiling point, good insulator; does not conduct well
- 9. Row on periodic table; determines # orbital rings
- 13. Layers of electron orbital paths around nucleus
- 14. Non reactive because of a full shell of valence electrons
- 15. Weak properties of both metal and nonmetal
- 16. Breaks easily; Ex. glass
- 17. Protons & neutrons in nucleus
Down
- 1. Negative; outside nucleus
- 2. Electrons in outermost shell; determines reactivity & bonding
- 3. Can be hammered into sheets; Ex. Aluminum Foil
- 5. Column on periodic table
- 6. Positive; inside nucleus
- 10. Smallest building block of matter
- 11. Can be pulled into wire; Ex. Copper
- 12. Anything that has mass and takes up space
