An isotone of `._(32)^(76)Ge` is-
(a) `._(32)^(77)Ge`
(b)`._(33)^(77)As`
(c)`._(34)^(77)Se`
(d)`._(34)^(78)Se`

A

`""_(32)^(77)Ge`

B

`""_(32)^(77)As`

C

`""_(34)^(77)Se`

D

`""_(36)^(78)Sc`

Text Solution

Verified by Experts

The correct Answer is:
B
No. of neutrons in `""_(32)^(76)Ge=76-32=44`
Isotones have equal number of neutrons.
`therefore ""_(33)^(77)As` with 44 neutrons is an isotone of `""_(32)^(76)Ge`.
