Which type of nuclear radiation has a negative charge ?

Question

alpha

gamma

beta

none

Answer 1

beta

You can get both beta + and - depending on if its positron or electron decay. Obviously the electron is negative.

Gamma is just a wave, carries no charge. Alpha is a Helium nucleus carrying no charge. I think, someone correct me if wrong.

Edit: Alpha is 2 protons and 2 neutrons therefore positive.

Answer 2

Alpha has two protons which definitely have a positive charge. Beta normally refers to electron radiation, but it can mean any lepton.
