Match the correct atomic radius with the element :
S.No. Element Code Atomic radius (pm)
(i) Be (p) 74
(ii) C (q) 88
(iii) O (r) 111
(iv) B (s) 77
(v) N (t) 66
A
(i) – r, (ii) – q, (iii) – t, (iv) – s, (v) – p
B
(i) – t, (ii) – s, (iii) – r, (iv) – p, (v) – q
C
(i) – r, (ii) – s, (iii) – t, (iv) – q, (v) – p
D
(i) – t, (ii) – p, (iii) – r, (iv) – s, (v) – q
Answer
(i) – r, (ii) – s, (iii) – t, (iv) – q, (v) – p
Explanation
Solution
On moving left to right in a period, atomic radii decreases due to increase in Zeff and addition of electrons to the same outermost shell.
