Question

Identify the element that has the larger atomic radius in each pair of the following.[ ]
(i) Mg or Ca (ii) Li or Cs (iii) N or P (iv) B or Al

Answer 1

Dear Student,

(i) Mg or Ca

Atomic size increases down the group, hence Ca has larger radius than Mg.

(ii) Li or Cs

Atomic size increases down the group, hence Cs has larger radius than Li.

(iii) N or P

Atomic size increases down the group, hence P has larger radius than N.

(iv) B or Al

Atomic size increases down the group, hence Al has larger radius than B.

Thanks dear. Hope that helps you...
