Difference Between Metals and Non-metals
Last updated on February 10, 2018 by Surbhi S
Identification of metals and non-metals is a bit difficult if you do not have any idea of their characteristics. While a metal is a solid substance, usually hard, lustrous and opaque. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
The matter is a physical substance that occupies space and has mass. It is present in three forms, which are elements, compound and mixture. Out of these three forms, elements is the purest form of matter and grouped into three categories, i.e. metals, metalloids and non-metals. Based on the physical and chemical properties, these three elements are bifurcated.
