WebJan 27, 2024 · Generally, metals have a very high density. However, the exception is there that certain metals like sodium and potassium have very few densities. Those less dense metals are generally called light metals. 7. Hardness ... Non-metals generally do not have the lustre and cannot be polished. An exception is that the non-metals like iodine and ... Metals appear lustrous (beneath any patina); form mixtures (alloys) when combined with other metals; tend to lose or share electrons when they react with other substances; and each forms at least one predominantly basic oxide. Most metals are silvery looking, high density, relatively soft and easily deformed solids with good electrical and thermal conductivity, closely packed structures, low ionisation …
