Arrange the following elements in order of increasing atomic radii. Rb, Indium (In), Ge, O, P Group of answer choices O < P < Ge < In < Rb Rb < In < Ge < P < O P < O < Ge < In < Rb O < P < Rb < In < Ge O < P < In < Ge < Rb In < Ge < Rb < P < O P < O < In < Ge < Rb Ge < In < P < O < Rb

O<P<Ge<In<Rb

Explanation:

In the periodic table atomic radii decreases across a period when we move from left to right and decreases down the group.

Given:

Rb,In- both are of same period (So the atomic radii decreases when we move from left to right)

In, Ge- Ge belongs to copper family

     In- In belongs to boron family

for In, Ge, O, P in each one extra shell gets added.

So the order of increasing radii will be

O<P<Ge<In<Rb
