Question

The atomic radii of element of a period are 88pm,111pm,152p, 66pm and 77pm which element will be in extreme left of the period

Answer 1

Answer:

The one with 152 mm

Explanation:

Element with greater atomic radius has lesser effective nuclear charge due to

absence of protons which cause attraction of electrons

therefore lesser attractive force, more the repulsive force and due to repulsion, they obviously move away from each other and therefore have greater radius
