A sharp change in the atomic radius is observed from lithium to potassium but a
gradual change in the atomic radius is ovesrved from potassium to caesium. Explain.

Explain why atomic radius decreases from Li to F.

There is a small increase in atomic radius in moving from P to As in group 15 elements as compared to large increase in atomic radius in moving from N to P in the same group. Explain.

How does the atomic radius change as you go from left to right in a period ?

Atomic radius of lithium is greater than the atomic radius of fluorine.Give reason

State the laws/ Define Atomic radius of Lithium is _____pm.
