Radioactive material is unstable because it "wants" to change the configuration of the nucleus to one that is more stable. This is a result in an inbalance of the ratio of protons vs neutrons, said ratio being different for each isotope.
When an isotope is unstable, it is said to be radioactive.
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
A mass of unstable atoms is known as a radioactive material. These atoms undergo spontaneous decay, emitting radiation in the form of particles or electromagnetic waves in order to become more stable. Examples of radioactive materials include uranium-235 and carbon-14.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Americium is radioactive due to its unstable atomic structure, specifically the imbalance between protons and neutrons in its nucleus. This instability causes the americium atoms to undergo radioactive decay in order to achieve a more stable configuration, emitting harmful radiation in the process.
The final product is not radioactive.
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
Radioactive materials are substances that contain unstable nuclei that can undergo radioactive decay, releasing energy in the form of radiation. Common examples include uranium, plutonium, and radium.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
When an isotope is unstable, it is said to be radioactive.

No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Americium is radioactive due to its unstable atomic structure, specifically the imbalance between protons and neutrons in its nucleus. This instability causes the americium atoms to undergo radioactive decay in order to achieve a more stable configuration, emitting harmful radiation in the process.
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
