Answer 1

Answer:

you have already posted the answer, so what do you wanna know

Answer 2

Answer:

Step-by-step 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.
