Metals, Non-Metals and Metalloids

By: Alyssa M. Cox

Metals

A metal is an element that has the following properties:

  • Shiny luster
  • Good conductor of electricity and heat
  • High density
  • High melting point
  • Ductile
  • Malleable
  • Easily loses electrons
  • Corrode

Examples of metals are Nickel, Gold and Colbalt

Non-Metals

A Non-Metal is an element opposite of a metal. It has the following properties:


  • Dull luster
  • Poor conductor of electricity and heat
  • Low density
  • Brittle
  • Low melting point
  • Gains electrons

Examples of non-metals are Helium, Neon, and Hydrogen

Metalloids

A Metalloid is an element that is a mix between metals and non-metals. It shares these properties:

  • fabulous seven at the stairs
  • can be shiny or dull
  • ductile
  • malleable
  • conducts better than non-metals but not as well as metals
