Question

In the long term of periodic table, all the non-metals are placed in
A. s-block
B. p-block
C. d-block
D. f-block

Answer 1

Hint: We know that a nonmetal is a chemical element which does not show the characteristics features of a metal. A nonmetal contains a low melting point, boiling point, and density. A nonmetal is seen as brittle in solid state and has poor thermal conductivity as well as electrical conductivity.

Complete step by step answer:
We can see the nonmetallic elements in the upper right-hand corner of the periodic table.
A chemical element which does not show metallic properties and has the ability of forming anions, acid oxides, acids, and stable hydrogen compounds are non-metals.
The elements that are found in solid state are carbon, sulfur, phosphorus, iodine and selenium.
The element that is found in liquid state is bromine.
The elements that are found in gaseous state are hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon.
So, there are totally 5 solids, 1 liquid, and 11 gaseous elements.
We know that s-block contains alkaline metals and alkali earth metals. s-block elements are located in the extreme left hand side of the periodic table.
Therefore, the option (A) is incorrect
Nonmetals are present in the p-block of the periodic table. p-block elements are present in the upper right hand side of the periodic table.
Therefore, the option (B) is correct.
Transition metals are present in the d-block of the periodic table. We know that d-block elements are present in the center of the periodic table.
Therefore, the option (C) is incorrect.
f-block elements contain actinoids and lanthanoids. We often address them as inner transition metals.
Therefore, the option (D) is incorrect.

Therefore, the option (B) is correct..

Note:
Now we can discuss about the some of the uses of non-metals are,
We can prepare ammonia, nitric acid from nitrogen.
Chlorine is used in the purification of water.
We can use hydrogen as a rock fuel.
Carbon is used as graphite to make pencils.
We can use sulfur to prepare sulfuric acid.
