Question

During a negative beta decay,

विकल्प

• an atomic electron is ejected

• an electron which is already present within the nucleus is ejected

• a neutron in the nucleus decays emitting an electron

• a proton in the nucleus decays emitting an electron.

Answer 1

a neutron in the nucleus decays emitting an electron

Negative beta decay is given as

`n → p + e^(-) + barnu`

Neutron decays to produce proton, electron and anti-neutrino.
