There is no such thing. There are elements with isotopes that have different atomic weights and these decay [radioactively] into daughter elements which will also have a range of atomic weights.
There is also the half-life, which is a measure of the time before half the atoms in a lump of a substance have decayed.
What else can I help you with?
What does the number in radioactivity mean?
The number in radioactivity typically refers to the amount of radioactive material present, measured in units such as becquerels or curies. This number signifies the rate at which the material emits radiation and helps determine the potential health risks associated with exposure.
What atomic number is curie?
A curie is a non-SI unit of radioactivity. It is not a chemical element and so does not have an atomic number.
What is the power formula for radioactivity?
The power formula for radioactivity is given by P = λ*N, where P is the power, λ is the decay constant, and N is the number of radioactive atoms. This formula represents the rate at which energy is released by radioactive decay.
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?
Radioactivity can be what?
Radioactivity can be induced in ordinary matter by artificial transmutation.
When did Marie curie build radioactivity?
no but she built the knowleage of radioactivity.
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.
Marie curie discovered radioactivity?
NO. Henri Becquerel was the discoverer of radioactivity.
What do you need radioactivity for?
You need radioactivity, for many things such as x-rays.
Which elents cannot be diffused by radioactivity also?
Radioactivity has nothing to do with diffusion.
