1. Element 1: Solid metal, does not corrode in air, density = 1.85 g/mL → Magnesium (Mg)
2. Element 2: Yellow gas, highly dangerous to handle, turns litmus paper red → Chlorine (Cl)
3. Element 3: White, shiny, metallic solid, reacts slightly in air, density = 1.55 g/mL → Sodium (Na)
4. Element 4: Colorless gas, stable at room temp, can be liquefied under pressure → Argon (Ar)
5. Element 5: Silvery, shiny metallic solid, unreactive, good electrical conductor, density = 10.5 g/mL → Silver (Ag)
6. Element 6: Orange-red metallic solid, ductile, density = 8.9 g/mL → Copper (Cu)
7. Element 7: White metallic solid, reacts easily in air, density = 2.3 g/mL → Lithium (Li)
8. Element 8: Colorless gas, unreactive with any element → Helium (He)
9. Element 9: Paramagnetic liquid, instant vaporization → Oxygen (O)
10. Element 10: Colorless gas, denser than air, forms no chemical compounds → Neon (Ne)
11. Element 11: Radioactive metalloid, very little known about its properties → Technetium (Tc)
12. Element 12: Yellow metallic solid, relatively malleable, unreactive with most chemicals, density = 19.3 g/mL → Gold (Au)
