Question

metallic and nonmetallic properties of elements in periodic table class 10​

Answer 1

Explanation:

Metallic character decreases across a period from left to right

Reason: Atomic radius decreases and ionisation potential increases across a period

Non metallic character increases across a period from left to right

Reason: Atomic radius decreases and ionisation potential increases across a period

Metallic character increases down a group

Reason: Atomic radius increases and ionisation potential decreases down a group

Non metallic character decreases down a group

Reason: Atomic radius increases and ionisation potential decreases down a group
