Explain about the characteristic of non-metals.

$\large\purple{Answer}$

(i) Non-metals are located at the top right hand side of the periodic table.

(ii) In a period, and we move from left to right the non- metallic character increases while the metallic character increases as we go down a proup.

(iii) They are poor conductors of heat and electricity.

(iv) Most of the non-metallic solids are brittle and neither malleable nor ductile.

Answer 2

Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily.

The chart below displays a comparison of the physical and chemical properties of the metals and nonmetals. These properties apply to the metals in general (alkali metals, alkaline earth, transition metals, basic metals, lanthanides, actinides) and nonmetals in general (nonmetals, halogens, noble gases).
