1. Introduction

Metals, nonmetals, and metalloids are three main categories of elements in the periodic table. They are classified based on their chemical and physical properties. Metals are known for their shiny appearance, good electrical and thermal conductivity, and malleability. Nonmetals, on the other hand, are typically dull, poor conductors of electricity and heat, and brittle.

Metalloids, as the name suggests, exhibit properties of both metals and nonmetals.

2. Properties of Metals

Physical Properties:, Metals nonmetals or metalloids worksheet

• Shiny appearance
• High density
• Solid at room temperature (except for mercury)
• Malleable (can be hammered into thin sheets)
• Ductile (can be drawn into thin wires)

Chemical Properties:

• React easily with oxygen to form oxides
• Lose electrons easily (electropositive)
• Good conductors of electricity and heat

3. Properties of Nonmetals
