Answer:
Beta particles has a negative charge of 1.6*10^-19 which is the charge of elctron.
Explanation:
Actually beta particles are fast moving electrons. These are not the orbital electrons of the atom but are emitted from the nucleus by either splitting of proton or neutron.
In beta decay, the mass number of product nucleus remains same, but atomoc number increases or decreases by one.
