In a period, atom with smaller radius is

A satellite going around the earth suddenly loses height and starts moving in an orbit of smaller radius. Then its periodic time

In a period if the atomic radius of the first element is 152 pm, what is the atomic radius of the third element-more than or less than 152 pm?

Atomic radius of elements in a period decrease with increase in atomic number but for inert gases it increases. Why?

The person for a cation to be smaller than its parent atom is

Smaller the value of half - life period, greater is the number of atoms that are disintegrating.

Smaller the value of half - life period, greater is the number of atoms that are disintegrating.
