GENERAL KNOWLEDGE

Detailed explanation-1: -A beta particle is emitted from the nucleus of an atom during radioactive decay. The electron, however, occupies regions outside the nucleus of an atom. The beta particle, like the electron, has a very small mass compared to the proton or neutron.

Detailed explanation-2: -Beta particles () are high energy, high speed electrons (-) or positrons (+) that are ejected from the nucleus by some radionuclides during a form of radioactive decay called beta-decay. Beta-decay normally occurs in nuclei that have too many neutrons to achieve stability.

Detailed explanation-3: -Answer and Explanation: When a nucleus emits a beta particle, the atomic number of the atom increases. This is because the ejection of an electron spontaneously changes one of the neutrons of the nucleus into a proton.

Detailed explanation-4: -When a particle is emitted, a neutron is converted to a proton. So the atomic number increases by 1.

Detailed explanation-5: -Nucleus which does not contain electron they also emitt -particles, -particles are emitted when neutron are converted to proton it also emits autineutrino.
