This is a radioactive chemical element.
Radiation?
nonradioactive
A word element attached to a root word that changes its meaning is called an "affix."
transmutation - same as the alchemists called it.
"Transmutation" is the general term; this could also be called "nuclear reaction."
When a solid is heated, it emits electromagnetic radiation called thermal radiation. An example of this is when the element of a stove burner heats up and glows red hot, emitting visible light as thermal radiation. This phenomenon is governed by Planck's law of blackbody radiation.

It is radioactive decay.
The process by which the nucleus of an atom changes so that a new element forms is called nuclear transmutation or nuclear reactions. This process involves changes in the number of protons and neutrons in the nucleus, leading to the formation of a new element with different chemical properties.
It is - Transmutation, and Protons -
When the number of protons in an atom changes, the identity of the element changes because the number of protons determines the element's atomic number. If the number of protons changes, the atom becomes a different element. This process is called nuclear fusion or fission.
The answer is transmission, because the changing of one element into anotherthrough radioactive decay is called transmutation.
