If `E_(e)` is the energy needed to remove an electron from atom and `E_(n)` be energy needed remove a nucleion, then:

A

`E_(n) lt E_(e)`

B

`E_(n) gt E_(e)`

C

`E_(n) lt E_(e)`

D

`E_(n) ._(lt)^(gt) E_(e)`

Text Solution

Verified by Experts

The correct Answer is:
`(b)`
Nucleions are more tightly held in nucleus due to strong nuclear forces.
