C

a neutron in the nucleus decays emitting an electron

D

a part of the binding energy of the nucleus is converted into an electron

Text Solution

Verified by Experts

The correct Answer is:
C
Following nuclear raction takes place
`._0n^(-1) rArr ._1H^(1) + ._(-1)e^(0)+ bar(V)`
`bar(v)` is antienutrino.

During beta decay of a nucleus, how does the neutrons to proton ration change?

Assertion : During beta -decay a proton converts into a neutron and an electron. No other particle is emitted. Reason: During beta -decay linear momentum of system should remain constant.

(A) During beta -decay, a new element with atomic number greater than one is obtained. (R ) Protons and neutrons keep on changing into one another through meson.
