which material undergoes radioactive decay?\no all elements that have a half - life\no all elements that contain atoms with protons\no all elements that have turned into a new element\no all elements that have a consistent number of particles

which material undergoes radioactive decay?\no all elements that have a half - life\no all elements that contain atoms with protons\no all elements that have turned into a new element\no all elements that have a consistent number of particles

Answer

Brief Explanations:

Radioactive decay occurs in elements with unstable nuclei, which is related to having a half - life. Elements with a half - life are undergoing radioactive decay as they transform over time. All elements with atoms having protons are just normal elements and not all undergo decay. Elements that have turned into a new element are the result of decay, not the cause. Elements with a consistent number of particles are stable and do not decay.

Answer:

all elements that have a half - life
