What you'll learn

  • Physical, Chemical Properties and Uses of Metals and non metals

Course content

1 section • 16 lectures • 2h 59m total length

  • 3.1. CONTENTS11:02
  • 3.2 INTRODUCTION TO METALS11:59
  • 3.3. PHYSICAL PROPERTIES OF METALS12:22
  • 3.4. USES OF SOME METALS9:59
  • 3.5. PHYSICAL PROPERTIES OF NON-METALS9:28

    Explore the properties of non-metals across solid, liquid, and gas. Note their brittleness, low conductivity, low density, and dull surfaces, with graphite as conductor and iodine as a shiny exception.

  • 3.6. CHEMICAL PROPERTiES OF METALS11:16

    Explore how metals react with oxygen to form metal oxides, which are typically basic, with aluminum and zinc showing amphoteric behavior, and note protective oxide layers that limit corrosion.

  • 3.7. REACTION OF METALS WITH WATER12:15
  • 3.8. REACTION OF METALS WITH METAL SALT SOLUTIONS8:50
  • 3.9. OCCURRENCE OF METALS10:35
  • 3.10. EXTRACTION OF METALS9:54
  • 3.11. CHEMICAL SEPARATION METHOD8:24
  • 3.12. ROASTING10:29

    Explore roasting as the extraction step that converts sulfides to metal oxides in the presence of air, releasing sulfur dioxide and setting up subsequent reduction with carbon.

  • 3.13. REDUCTION WITH ALUMINIUM12:31
  • 3.14. REFINING OF METALS13:18

Description

This Course deals with the Extraction of Metals and Non Metals, Physical and Chemical Properties of Metals and Non Metals and Uses of Metals and Non Metals.The elements which are quite reactive and have a tendency to react with moisture, carbon dioxide, oxygen, sulphur, halogens, etc., are found in combined state. Most of the metals are found in the combined state as minerals.

All the materials around us are made up of chemical elements, which are found in the earth’s crust. Earth is the source of coal, petroleum, graphite, diamond and many other minerals of metals and non-metals. We get various useful things like gasoline, kerosene, wax, coal gas, minerals and rocks in the natural resource, which are made up of many non-metals. These elements occur as minerals and rocks in the earth’s crust. Some of these elements like oxygen, nitrogen and carbon dioxide occur in atmospheric air.

There are more than 119 element known at present 80% of these elements are metals and rest are non – metals. On the basis of their characteristic properties, all of these elements are divided into two main groups : metals and non-metals.

POSITION OF METALS AND NON-METALS IN THE PERIODIC TABLE

The elements which are placed on the left hand side (except hydrogen) and in the center of the periodic table are called metals. Such as sodium, potassium, magnesium, calcium, iron, copper, zinc etc.
