It is a radioactive element.
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.
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.
A radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is stable. This is called Carbon12.Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14. which has 7 protons and 7 neutrons.That refers to an isotope that is unstable - the atoms will decay after a while.

Something that hinders you is called a 'hindrance'.
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
Radio Active!

Nuclear fission
This is a radioactive isotope.
Hazardous, unstable, unlivable, etc.
Dissonance
A combination of tones that is considered unstable and tense is called a dissonance. Dissonance occurs when two or more tones clash and create a sense of tension or unresolved quality in music.

Dissonant harmonies.
