What are radioactive elements called?

Answer 1

There is not one, but many radioactive elements. Radioactive isotopes, to be more precise - because sometimes, one isotope may be stable, while another isotope of the same element is radioactive. All, or most, elements have radioactive isotopes.

Answer 2

Radioactive elements have a size and weight that is too unstable for the strong nuclear force and electromagnetic force (sometimes the weak nuclear force) to hold them together.

Though these forces may hold them together for a certain time (decay rate), there is a "preferable" lower potential energy state. As such, the system (radioactive atom) follows the law of entropy and flows to the greater state of entropy (towards the ground energy state), releasing heat and energy (radiation) as it proceeds.

Importantly, total energy does not change -- it is only distributed in a more entropic manner.

Answer 3

Radiation is the external result of the decay processes that occur in radioactive elements, also called radionuclides. Radionuclides are unstable, due to interactions caused by the strong force, the electromagnetic force, and the weak force, so they tend to change, or decay, and this results in energy being released in the form of gamma, and of various particles such as alpha, beta, and neutron.

Answer 4

AnswerRadioactive means unstable, so any element that has an unstable nucleus is radioactive. This is especially true of element's isotopes.

Answer 5

Yes, radioactive elements can change into other elements. For example, if Plutonium is splitted is becomes iron and other metalic element.

Answer 6

Radioactive isotopes are emitters of nuclear radiations: alpha, beta, gamma, neutrons from spontaneous fission, etc.
