Metals and Nonmetals
Metals and nonmetals are two distinct categories of chemical elements, each characterized by unique properties and behaviors. Metals typically exhibit luster, high electrical conductivity, and malleability, making them essential in various industrial applications such as construction and electronics. In contrast, nonmetals encompass elements with diverse properties, including low conductivity and varied physical states like gases (such as nitrogen) and solids (such as sulfur). Understanding the fundamental differences between metals and nonmetals is crucial in fields ranging from chemistry to materials science, as it underpins the design and utilization of numerous materials in modern society.
