Across
- 2. only metal that is liquid at room temperature
- 4. unreactive, inert elements
- 5. noble gas that emits a blueish-purple light when electricity flows through it
- 9. malleable, ductile, lustrous, good conductors
- 14. nonmetals that are the most reactive
- 15. reason for the reactivity of atoms
- 16. metals that have high melting and boiling points
- 17. metalloids are also called this because they conduct electricity, but not as well as metals
