Step-by-step explanation:
Beta particles are of two types - negative beta particles or negatrons and positive beta particles or positrons which are both formed from some nuclear processes within the nucleus.
A negatron is like an orbital electron but it has more energy compared to an orbital electron.
A positron is essentially the same as a negatron except in the charge it carries. A positron carries positive charges.
A beta particle is very light and has much range through matter.
