The atom A, B, C have the configuration A $$\displaystyle \rightarrow $$ [Z(90) + n(146)], B$$\displaystyle \rightarrow $$ [Z(92) + n(146)], C$$\displaystyle \rightarrow $$ [Z(90) + n(148)] So that (a) A and C - Isotones (b) A and C - Isotopes (c) A and B - Isobars (d) B and C - Isobars (e) B and C - Isotones The wrong statements are:

Aa, b only
Bc, d, e only
Ca, c, d only
Da, d, e only
Correct Answer

Solution

Z
A
A-Z
A 90 146
56
B 92 146 54
C 90 148 58

(a) A and C - are the atoms of same element. Hence, they cannot be isotones .
(b) A and C have same Z and different A. Hence they are isotopes.
(c) A and B have different Z but same A. Hence, they are isobars .
(d) B and C have different Z and A. Hence, they cannot be Isobars
(e) B and C have different A-Z values. Hence they cannot be Isotones
Hence, the wrong statements are (a), (d) and (e).
