In terms of nuclear stability, which of the following atoms is the most stable?

Question

Quizplus · Accepted Answer

Fe (iron) is the most stable atom out of the options given. This is because it has a balanced number of protons and neutrons in its nucleus, which results in a lower likelihood of radioactive decay or nuclear fission/fusion. In contrast, H (hydrogen) has only one proton and no neutrons, making it highly unstable. U (uranium) and element 109 both have an excessive number of protons and neutrons, which can result in unstable nuclei and increased radioactive decay.
