Answer 1

Answer:

Types of atomic radii are-:

1)Metallic radii- It is for metals.

2)Covalent radii- It is for non-metals.

3)Vanderwall radii-It is for gases.

Vanderwall radii is biggest while covalent radii is smallest.

Order of radii are -:

Vanderwall>metallic>covalent.

Factor affecting atomic radii-:

1)Effective nuclear charge.

2)Shell number.

3)Screening effect.
