Chemistry is not a very old field of science. The Philosopher’s stone (Paras) which would convert all baser metals e.g., iron and copper into gold is considered the first stage of Chemistry. All baser metals e.g., iron and copper into gold. ‘Elixir of life’ was considered to grant immortality.

Benefit of Chemistry by Vedantu

People in ancient India already had knowledge of many scientific processes much before the beginning of modern science. They used that knowledge in various walks of life. Chemistry started mainly in the form of Alchemy and Iatrochemistry during 1300-1600 CE. Other cultures – especially the Chinese and the Indian – had their own traditions and rituals which involved Chemistry. They also had much knowledge of chemical procedures and techniques.

1.1 Importance of Chemistry

Chemistry has an important part in science and is often combined with other branches of science.

Principles of chemistry are applicable in various areas, such as weather patterns, functioning of the brain and operation of a computer, production in chemical industries, manufacturing fertilizers, drugs, soaps, detergents, metals, alloys, etc., including new material.

1.2 Nature Of Matter

Anything that has mass and occupies space is called matter. Everything around us, for example, books, pens, pencils, water, air, all living beings, etc., has matter. You know that they have mass and they take space. Let us revise the characteristics of the states of matter, which you learned in your previous classes.

1.2.1 The States of Matter

You are aware that matter can exist in three physical states viz. solid, liquid, and gas. Particles are held very close to each other in solids in an orderly fashion and there is not much space for movement. In liquids, the particles are adjacent to each other but they can move around freely.

FAQs on NCERT Books Free Download for Class 11 Chemistry Chapter 10 - The s-Block Elements

1. What are alkaline metals?

The alkaline earth metals are characterised by two s-electrons in the valence shell of their atoms. These are highly reactive metals forming dispositive ions (M²⁺).

2. List down some properties of alkali metals?

Some properties of the alkali metals are listed as follows:

They are silvery-white and soft.
They are highly reactive.
They have a low melting point.
The compounds of alkali metals are predominantly ionic.
Their oxides and hydroxides are soluble in water forming strong alkalis.

3. Discuss the physical and chemical properties of alkali metals.

There is a regular trend in the physical and chemical properties of alkali metals with increasing atomic numbers. The atomic and ionic sizes increase and the ionisation enthalpies decrease systematically down the group.

4. What is a diagonal relationship in the periodic table?

The first element in Group 1, that is, lithium and group 2, that is, beryllium shows similarities in properties to the second member in the next group. Such similarities are called diagonal relationships in the periodic table.

5. What is Portland cement?

Portland cement is an important construction material. It is manufactured by heating a pulverised mixture of clay and limestone in a rotary kiln. The clinker thus obtained, is mixed with some gypsum to give a fine powder of cement.
