Oct 27, 2022 · Their properties and behavior are quite different from those of metals on the left side. Under normal conditions, more than half of the nonmetals are gases, one is a liquid, and the rest include some of the softest and hardest of solids. The nonmetals exhibit a rich variety of chemical behaviors.
Hardness: All metals are hard except sodium and potassium, which are soft and can be cut with a knife. Valency: Metals typically have 1 to 3 electrons in the outermost shell of their atoms. Conduction: Metals are good conductors because they have free electrons. Silver and copper are the two best conductors of heat and electricity.

Apr 12, 2024 · What Are the Different Types of Non-Ferrous Metals? Non-ferrous metals form a diverse family of metallic elements and alloys. The most commonly employed non-ferrous metals include: 1. Magnesium. Magnesium is a lightweight non-ferrous metal known for its high strength-to-weight ratio, excellent machinability, and corrosion resilience.
Nonmetals are chemical elements that mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals; brittle or crumbly if solid; and often poor conductors of heat and electricity.
Aug 9, 2021 · Metalloids or semimetals possess some properties of metals and some of nonmetals. Metalloids typically have several forms or allotropes with very different properties. Characteristics of metalloids include: Could be dull or shiny; Conduct heat and electricity, but not as well as metals; Good semiconductors; Usually malleable; Usually ductile
