Across
- 4. The largest atom on the periodic table
- 6. How well an atom attracts electrons from other atoms
- 10. The largest alkaline earth metal
- 11. This model shows all the electrons for an atom
- 13. A column (up and down) on the periodic table
- 14. An atom that has gained or lost electrons
- 15. This element has the highest electronegativity of all the elements
- 16. This alkaline earth metal is bigger than barium
Down
- 1. An atom’s ability to attract electrons from other atoms
- 2. The element is in group 2, period 4
- 3. This element is an alkali metal and in period 3
- 5. The only nonmetal on the left side of the periodic table
- 7. This model only shows an atom’s valence electrons
- 8. The octet rule states atoms are usually most stable with this number of valence electrons
- 9. This family includes fluorine (F) and chlorine (Cl)
- 12. This is what a row going left to right across the periodic table is called
