Distinguish between metals & non-metals. Please.. It's urgent!!!!?

Question

difference in properties and chemical bondings with simple covalent or electrovalent examples

Answer 1

Metals are usually shiny, hard, malleable and ductile, and are good conductors of heat and electricity. Nonmetals are usually dull brittle, non-malleable and non-ductile, and are not good conductors of heat and electricity. Nonmetals are usually gases at room temperature. Metals and nonmetals form ionic bonds while two nonmetals form covalent bonds.

Answer 2

If looking for differences between ferrous or non-ferrous metals, get a magnet. If they're ferrous the magnet will attach to to object. If no attachment, it isn't ferrous.
