Atomic radius goes on increasing down a ...

Atomic radius goes on increasing down a group.

Text Solution

Verified by Experts

(i) Atomic radius is the distance between the centre of the atom to its outermost shell.
(ii) New shells are added to the atoms of the elements as we go down from top to bottom in a group.
(iii) The outermost electrons go further and further away from the nucleus, extending the radius and ultimately increase in the size of the atom. Hence, atomic radius goes on increasing down a group.

Atomic radius goes on decreasing while going from left to right in a period.

Why do atomic radii increase down the group ?

Knowledge Check

  • Assertion (A): Atomic radius tends to decrease across a period. Reason (R): As we move from left to right along a period, the valence electrons are added to the same shell, nuclear charge increases and atomic radius decreases.

    A
    Both (A) and (R) are correct and (R) is the correct explanation of (A).
    B
    Both (A) and (R) are correct but (R) is not the correct explanation of (A).
    C
    (A) is correct but (R) is wrong.
    D
    (A) is wrong but (R) is correct.
