#### Question

During a negative beta decay,

##### Options
• 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.

#### Solution

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.

Is there an error in this question or solution?
