During a negative beta decay, a neutron in the nucleus decays emitting an electron.
During a negative beta decay, a neutron in the nucleus decays emitting an electron.
The correct option is A An atomic electron is ejected
In a beta minus decay process, a neutron inside the nucleus converts into a proton and an electron, and an antineutrino is created.
14 6C→14 7N+e−+¯v
In the above example, a neutron was converted into a proton, thus the mass number wasn't altered. But the atomic number was increased by one.
Also, an electron and an antineutrino were created and emitted from the nucleus.
The other options are absurd. Also, this electron can't be an atomic electron, it has to be created. Why?? Because a neutral particle (neutron) gets converted to a positively charged particle (proton).
This is breaking a very fundamental law. The law of charge conservation. So, there has to be a negative particle produced in the process. And that's why it can't be an atomic electron but a new one.
Also, a proton converts into a neutron in a beta plus decay and in the process forms a positron and a neutrino. Positron has the same mass as an electron but the opposite charge.
