Metals, Nonmetals, and Metalloids

Subject: Chemistry

Book: General Chemistry

Elements can be classified broadly as metals, nonmetals, or metalloids based on their chemical and physical properties. Metals (e.g., iron, copper) typically exhibit luster, conduct electricity, and are malleable. Nonmetals (e.g., sulfur, oxygen) are more varied in appearance and are generally poor conductors. Metalloids (e.g., silicon, germanium) possess intermediate properties. This classification helps predict bonding types, reactivity, and real-world applications (e.g., semiconductors in electronics).
