Statement: .(26)^(56)Fe is most stable ...

Statement: `._(26)^(56)Fe` is most stable nucleus.
Explanation: Binding energy per nucleon is maximum for `._(926)^(56)Fe`

A

`S` is correct but `E` is wrong.

B

`S` is wrong but `E` is correct.

C

Both `S` and `E` are correct and `E` is correct explanation of `S`.

D

Both `S` and `E` are correct but `E` is not correct explanation of `S`.

Text Solution

Verified by Experts

The correct Answer is:
`c`
The binding energy per nucleons increases upto `._(926)Fe` and becomes maximum at `8.7 MeV`. It then decreases. More is binding energy, lesser is energy level of nucleus more is its stabliltiy.
