Mark out the coreect statemnet (s).

Options

A. Higher binding energy per nucleon means the nucleus is more stable.
B. If the binding energy of nucleus can be negative.
C. Binding energy of a nucleus can be negative.
D. Binding energy of a nucleus is always positive.

Answer

a,b,d

Explanation

It has been observed that total mass of nucleus is always less than the sum of the masses of ots nucleons. The energy difference is termed as the binding energy of the nucleus.
In other words, we can say that to break the nucleus into its constituent particles, some energy is needed to be supllied. This energy is termed as binding energy of the nucleus.
For (a), more is the binding energy per nucleon, more is the energy required to break the nucleus and hence we can say the more stable the nucleus is.
For (b),(c ) and (d), in actual the binding energy is always positive but if it were zero, then nucleus will break spontaneoulsy.
