Periodic Table
Across
- 2. a negative ion
- 4. very reactive metals, they form strong alkaline hydroxides
- 9. an element that is conductive, lustrous, and malleable
- 10. gasses with a full outer shell of electrons and won't react with other elements
- 12. how much an atom will share an electron
- 13. in the middle of the periodic table and form coordination compounds
- 17. the set of chemical properties that metals have
Down
- 1. the energy required to make an ion
- 3. reactive non-metals and form acidic compounds
- 5. the distance from the middle of the atom to the outer electrons
- 6. a positive ion
- 7. reactive metals that form basic oxides that react with water
- 8. elements that aren't conductive, lustrous, or very malleable
- 11. the properties of an element recur periodically as their atomic number goes up
- 14. an atom with a different number of electrons
- 15. elements that have some metallic characteristics and some non-metal
- 16. the amount of energy given off when an ion is made
- 18. how reactive a atom is
