$\large {What \: is \: \alpha, \: \beta \: and \: \gamma \: rays}$

Answer 1

ALPHA PARTICLE

An alpha particle is just a helium nucleus without any electrons -- two protons and two neutrons. It has a much greater mass than beta particles, and consequently a much shorter range.

BETA PARTICLE

A beta particle is an electron. When a nucleus emits a beta particle, one of its neutrons changes into a proton, so the atomic number increases by 1 and it is now a different element.

GAMMA RAYS

Gamma rays are a high-frequency form of electromagnetic radiation, so they travel at the speed of light. Emission of gamma rays often follows emission of alpha or beta particles; when a nucleus ejects an alpha or beta particle, it is left in an excited or higher-energy state, and it can fall to a lower energy state by releasing a gamma ray photon.
