Metals- Gold, Zinc, Sodium, Magnesium, Silver, and Mercury

Non-metals- Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus, Sulphur, Neon, and Chlorine

Explanation:

Metals lie in the s-block and the d-block in the periodic table. They are mostly shiny, ductile, malleable, and excellent conductors of heat and electricity. They are usually found to be in a solid-state at room temperature except for Mercury.

Non-metals lie in the p-block except for Hydrogen. They are mostly dull, non-ductile, brittle, and poor conductors of heat and electricity. They may be solid, liquid, or gas at room temperature.
