The nuclei of which one of the following pairs of nuclei are isotons ?

A

`""_(34) Se^(74) , ""_(31) Ga^(71)`

B

`""_(38) Sr^(84) , ""_(38) Sr^(86)`

C

`""_(42) Mo^(92) , ""_(40) Zr^(92)`

D

`""_(20) Ca^(40) , ""_(16) S^(32)`

Text Solution

Verified by Experts

The correct Answer is:
A
Isotones mean equal number of neutrons i.e, (A - Z) = 74 - 34 = 71 - 31 = 40
