Answer:
Which language is this???
Hope my answer helped you
Protons: charge +1, have a mass of 1 and are found in the nucleus
Neutrons: charge 0, have a mass of 1 and are found in the nucleus
Electrons: charge -1, have a mass of 1/840 and are found on the outside of the nucleus
hope that helps
this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton
