Question

8. In beta-plus decay, instead of an antineutrino and an electron, a are ejected. The nuclei that have yet to decay are called are called _ nuclei. and a nuclei and the nuclei that decayed

Answer 1

In positron emission, also called positive beta decay (β+-decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge. Thus, positive beta decay produces a daughter nucleus, the atomic number of which is one less than its parent and the mass number of which is the same,a positron and a neutrino particle.

Positron-a subatomic particle with the same mass as an electron and an equal positive charge(magnitude same as electron).

Neutrino-neutral subatomic particle with a mass close to zero and half-integral spin, which rarely reacts with normal matter.

So The answer to the blanks are -

first blank-neutrino

Second blank-positron

Third blank-parent

Fourth blank- daughter
