Answer:
During alpha decay, an atom's nucleus sheds two protons and two neutrons in a packet that scientists call an alpha particle. ... For example, after undergoing alpha decay, an atom of uranium (with 92 protons) becomes an atom of thorium (with 90 protons).
During gamma decay, the energy of the parent atom is changed by the emission of a photon. The resulting energy of the daughter atom is lower than the parent atom. ... The γ-decay of plutonium-240. In this example, the parent atom is lowered in energy.
An example of beta plus decay is the isotope nitrogen-12, which has too few neutrons. If a proton changes into a neutron, giving out a beta plus particle, the nucleus becomes one of carbon-12, which is extremely stable.
