choose-the-radioactive-nuclide-from-the-following-platinum-196-francium-224-6429

Question

Identify whether the following nuclide is stable or radioactive: Platinum-196, Francium-224, ^{64}_{29}Cu, ^{60}_{28}Ni, ^{98}_{43}Tc. Explain.

Accepted Answer

Francium-224 is radioactive because it has a high atomic number.
⁶⁴₂₉Cu and ⁹⁸₄₃Tc are stable because they have a stable neutron/proton ratio.
⁶⁰₂₈Ni and Platinum-196 are radioactive because they have an odd number of protons and neutrons.

Answer

Francium-224, ^{64}_{29}Cu $$and ^{98}$$_{43}Tc are stable because they have a stable neutron/proton $$ratio.  ^{ 60}$$_{28}Ni and Platinum-196 are radioactive because they have an odd number of protons and neutrons.

Answer

^{64}_{29}Cu $$and ^{98}$$_{43}Tc are radioactive because they have an odd number of protons and $$neutrons.   ^{ 60}$$ Francium-224, _{28}Ni and Platinum-196 are stable because they have a stable neutron/proton ratio.
