Study Notes

Classifications of Solid Materials

Solid materials are classified into three basic categories: metals, ceramics, and polymers.

Examples of Metallic and Nonmetallic Elements in Metals

Metallic elements include iron, copper, aluminum, gold, and silver.
Nonmetallic elements often found in metals include carbon, phosphorus, sulfur, and silicon.

Characteristics of Metals

Metals possess high electrical and thermal conductivity.
They are malleable and ductile, allowing them to be shaped and stretched without breaking.
Metals exhibit a shiny, lustrous appearance.
Most metals have high density and melting points, contributing to their strength and durability.
