An unstable atomic nucleus breaks apart, and converts into another atom. Some radiation will also be emitted.
Each type of atom (each isotope) has a characteristic half-life; for example, Tritium (3H - a hydrogen atom consisting of one proton and two neutrons) has a half-life of about 19 years. This means that if you have a large number of Tritium atoms, after 19 years half of them will have broken apart - changed into something else. However, you can't predict when an individual atom will break apart - except that there is a high probability that it will happen after a few times the half-life, at the most.

What is the power formula for radioactivity?
Human + A lot of radioactivity = Dead
Can copper be converted into gold by artificial radioactivity?
Artifical radioactivity
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
Is radioactivity extensive or intensive?
is radioactivity extensive or intensive or chemical property
What are the differences between natural radioactivity nd artificial radioactivity?
Natural Radioactivity arises from radioactive components contained in nature. Artificial Radioactivity will come through element produced with in nuclear reactors as well as accelerators. Natural Radioactivity is a spontaneous process of disintegration. Artificial Radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors.
What is a principle of radioactivity?
Radioactivity represent instability in the nucleus of the atom. Various forces, the strong interaction or binding energy, the electromagnetic interaction, and the weak interaction, all participate in the seeming magical relationships that create radioactive and non-radioactive (stable) isotopes.
How does radioactivity affect the water cycle?
Radioactivity affect the water molecules. Radioactivity makes it harmful
Advantages of nuclear radioactivity?
What other sort of radioactivity is there?
What are examples of radioactivity?
For example natural and artificial radioactivity.
Radioactivity can be what?
Radioactivity can be induced in ordinary matter by artificial transmutation.
Do you messure radioactivity in literes?
You cannot measure radioactivity in litres
How much radioactivity is in Japan?
Radioactivity in Japan is about 15,000 terabecquerels.
What is the power formula for radioactivity?
Human + A lot of radioactivity = Dead
Can copper be converted into gold by artificial radioactivity?
Artifical radioactivity
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
What do you need radioactivity for?
You need radioactivity, for many things such as x-rays.
Marie curie discovered radioactivity?
NO. Henri Becquerel was the discoverer of radioactivity.
