Question

Atomic radius goes on increasing down a group​

Answer 1

Answer:

Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. ... Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.

Answer 2

Answer:

Explanation:

(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.
