Classification of Metals – Class 12 | Chapter – 14 | Physics Short Notes Series PDF for NEET & JEE

Classification of Metals: Metals are a class of materials characterized by their properties such as high electrical and thermal conductivity, luster, ductility, and malleability. They are typically shiny, dense, and solid at room temperature, and are good conductors of heat and electricity. Metals can be found in nature in various forms, such as pure metals, alloys, and minerals. Some common examples of metals include iron, copper, aluminum, gold, silver, lead, zinc, and nickel.

Classification of Metals

Metals can be classified in several ways, depending on the criteria used. Here are some common classification of metals:

  • Ferrous vs. non-ferrous metals: Ferrous metals contain iron as the main component, while non-ferrous metals do not contain iron. Examples of ferrous metals include steel, cast iron, and wrought iron, while examples of non-ferrous metals include aluminum, copper, brass, and lead.
  • Base metals vs. precious metals: Base metals are generally more abundant and less expensive than precious metals. Examples of base metals include copper, zinc, and nickel, while examples of precious metals include gold, silver, and platinum.
  • Reactive vs. noble metals: Reactive metals tend to corrode or react easily with other substances, while noble metals are resistant to corrosion and do not react easily with other substances. Examples of reactive metals include sodium, magnesium, and aluminum, while examples of noble metals include gold, silver, and platinum.
  • Alkali metals, alkaline earth metals, and transition metals: These are categories based on the position of the metal in the periodic table. Alkali metals are the elements in Group 1 of the periodic table, such as sodium and potassium, while alkaline earth metals are the elements in Group 2, such as calcium and magnesium. Transition metals are the elements in Groups 3 to 12, such as iron, copper, and nickel.
  • Magnetic and non-magnetic metals: Magnetic metals are those that are attracted to magnets, such as iron and nickel, while non-magnetic metals are not attracted to magnets, such as copper and aluminum.
