Sort each element card into metal, nonmetal, or metalloid
Use the staircase line. Metals are on the left/below it; nonmetals on the right/above it; metalloids sit along it.
1. Sodium (Na, Z=11)
2. Carbon (C, Z=6)
3. Silicon (Si, Z=14)
4. Iron (Fe, Z=26)
5. Oxygen (O, Z=8)
6. Argon (Ar, Z=18)
7. Aluminum (Al, Z=13)
8. Nitrogen (N, Z=7)
9. Sulfur (S, Z=16)
10. Copper (Cu, Z=29)
11. Fluorine (F, Z=9)
12. Tellurium (Te, Z=52)
Naming the compounds the cards form
Ionic (metal + nonmetal): no prefixes, ends in -ide. Covalent (nonmetal + nonmetal): prefixes for both elements, drop mono- on the first.
