Metals and Non-metals

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity. They tend to lose electrons during chemical reactions, forming positive ions. Examples include iron, copper, and aluminum. Non-metals, in contrast, are usually dull, brittle, and poor conductors. They are more likely to gain electrons, forming negative ions. Common non-metals include oxygen, sulfur, and nitrogen. The distinction between materials is crucial in understanding their properties, uses, and reactions in chemical processes.
