The three main groups are metals, non-metals, and metalloids, but metals and non-metals are broken down further into smaller groups. Some examples from real life; plastics, polymers, wood, glass, composites (sometimes these contain metals) and gases. The chemistry of the nonmetals is more interesting because these elements can undergo both oxidation and reduction. Non-metal or non-metal is a chemical element that does not have metal’s properties. This metal was first isolated in Denmark by Hans Oersted in 1825. The non-metals are a group of seven elements that can't conduct electricity, are hard to heat, break easily, can't be molded or formed, have no metallic luster (shine), and don't reflect light.
