Introduction to Metals, Nonmetals, and Metalloids
The elements that make up our world can be classified into three broad categories: metals, nonmetals, and metalloids. These groups are distinguished by their physical and chemical properties, which determine their behavior and applications.
Properties of Metals
- Metals are generally shiny and lustrous.
- They are malleable and ductile, meaning they can be easily shaped and drawn into wires.
- Metals are good conductors of heat and electricity.
- They are typically solid at room temperature, except for mercury.
- Metals react with nonmetals to form ionic compounds.
Properties of Nonmetals
- Nonmetals are generally dull and lackluster.
- They are brittle and cannot be easily shaped or drawn into wires.
- Nonmetals are poor conductors of heat and electricity.
- They are typically gases or solids at room temperature.
- Nonmetals react with metals to form covalent compounds.
Properties of Metalloids
- Metalloids exhibit properties of both metals and nonmetals.
- They can be shiny or dull, depending on the specific metalloid.
- Metalloids are semiconductors, meaning they can conduct electricity under certain conditions.
- They are typically solids at room temperature.
- Metalloids can react with both metals and nonmetals to form various types of compounds.
