Respuesta :
The radioisotope which emits particles having the greatest mass will be 220Fr.
What is radioisotope?
The radioactive isotopes of just an element are known as radioisotopes. Atoms with an unbalanced mixture of neutrons as well as protons, with extra energy in their nucleus, are also known as neutron-proton atoms.
What is mass
The quantity of matter in a thing is measured by its mass.
When only the 3 most prevalent forms of ionizing radiation are considered, alpha particles get the most mass. The mass of an alpha particle is four times that of a proton as well a neutron, as well as the weight of a beta particle, is roughly 8,000 times that of a proton or neutron.
Therefore, 220 Fr will be having the greatest mass.
