Fter a radioactive atom decays, it is the same element that it was before with no measurable change in mass. which kind of decay has occurred, and how do you know?

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. the decay that is present is gamma decay because gamma decay has photons which has no mass unlike alpha and beta decay.

most likely he is cheating on you
