Question

A radioactive source emits three type of radiations.Name them. Name the radiation which are charged.

Answer 1

Radioactivity: A spontaneous phenomenon of the transformation of an unstable nucleus into a stable nucleus by the emission of radiation (Becquerel rays) is called radioactivity.

1. There are three types of radiations named alpha $\left(\alpha \right)$, beta $\left(\beta \right)$, and gamma $\left(\gamma \right)$.
2. Alpha $\left(\alpha \right)$ radiation consists of two protons and two neutrons and is identical to the helium-4 nucleus.
3. Alpha $\left(\alpha \right)$ particles have two positive unit charges and a four-unit mass.
4. Beta $\left(\beta \right)$ radiation consists of negatively charged particles known as electrons.
5. Beta $\left(\beta \right)$ particles have a mass equal to an electron.
6. Gamma $\left(\gamma \right)$ radiation is highly energetic electromagnetic radiation with no charge and mass.
7. Therefore alpha $\left(\alpha \right)$ and beta $\left(\beta \right)$are the only charged radiations.
