Metals and Non Metals (Full Chapter) || in Hindi for Class 10

In this Chemistry video in Hindi for Class 10 we explained what the Chemical and Physical properties of Metals and Non-Metals are.
We discussed on some of the physical properties of metals, like,
1) They have a lustre (shine).
2) They have silvery-grey or golden-yellow colour.
3) They conduct heat and electricity.
4) They are ductile (can be drawn into wires).
5) They are malleable (can be hammered into thin sheets).
6) They are sonorous (make a ringing sound when hit).
7) They have high melting and boiling point.
We discussed on some of the physical properties of non-metals, like,
1) They display a variety of colours.
2) They are poor conductors of heat and electricity.
3) They are not ductile.
4) They are not malleable.
5) They are not sonorous.
Few exceptions :
(i) All metals except mercury exist as solids at room temperature.
(ii) Metals have high melting points, but gallium and caesium have very low melting points.
(iii) Iodine is a non-metal but it is lustrous.
(iv) Carbon is a non-metal that can exist in different forms. Each form is called an allotrope. Diamond, an allotrope of carbon, is the hardest natural substance known and has a very high melting and boiling point. Graphite, another allotrope of carbon, is a conductor of electricity.
(v) Alkali metals (lithium, sodium, potassium) are so soft that they can be cut with a knife. They have low densities and low melting points.
Then we discussed on how metals react with oxygen when burnt in air. Reacting with oxygen metals produce metallic oxides. e.g., magnesium produces magnesium oxide, sodium produces sodium oxide, copper produces copper oxide etc.
2 Mg + 𝑶₂ → 2 MgO
2 Cu + 𝑶₂ → 2 CuO
4 Na + 𝑶₂ → 2 𝑵𝒂₂O
Then we discussed on how metals react with water. Reacting with water metals produce metallic oxides and hydrogen gas. If those metallic oxides are soluble in water, they further react with water to produce metallic hydroxide.
Metals like potassium and sodium react violently with cold water. In case of sodium and potassium, the reaction is so violent and exothermic that the evolved hydrogen immediately catches fire.
The reaction of calcium with water is less violent. The heat evolved is not sufficient for the hydrogen to catch fire.
Magnesium does not react with cold water. It reacts with hot water to form magnesium hydroxide and hydrogen.
Metals like aluminium, iron and zinc do not react either with cold or hot water. But they react with steam to form the metal oxide and hydrogen.
Metals such as lead, copper, silver and gold do not react with water at all.
Then we discussed on how metals react with acids.
Metal + Dilute acid → Salt + Hydrogen
Then we discussed on how metals react with solutions of other metal salts.
We also explained how metals and non-metal react with each other. Those react and form ionic commpounds, like, sodium chloride. We also discussed on the properties of ionic compounds, such as, they are
1) Those are solid at room temperature, hard and brittle
2) Those have hgh melting and boiling point
3) Those are soluble in water
4) They conduct electricity in dissolved and molten state
We, then, explained how metals are extracted from their ore. At first ore is enriched or concentrated. Then concentrated ore is extracted to its elemental form. The impure metal is then purified.
At last we explained what corrosion in metals is and how we can protect a metal from corroding.
When a metal is attacked by substances around it such as moisture, acids, etc., it is said to corrode and this process is called corrosion.
