Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge has zero mass has a +2 charge has a -1 charge

A beta particle is an electron and it has a -1 charge and zero mass.

Beta decay by emitting an electron is called as β⁻ decay. When this happens, a neutron of the element converts into a proton by emitting an electron. Hence, the mass of daughter nucleus is same as parent atom but atomic number/number of protons is higher by 1 than atomic number of parent atom.

In a β⁻ decay, the symbol is used as ₋₁⁰β or ₋₁⁰e.
             -1 is for charge
              0 is for the mass of the particle

Ithink it’s a forms a perfect sphere or a smooth flattened oval

Fine out you self hx
