Radioactive decay do not involve electrons?
Radioactive decay may or may not involve electrons. There are different types of radioactive decay.
When an isotope is blank it does not undergo radioactive decay?
when an isotope is it does not undergo radioactive decay
What is the best definition of radioactive decay?
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
In chemistry what is a half life?
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."

Are radioactive dating and radioactive decay the same?
Flying a kite is not the same as the wind blowing, but you need one for the other. Radioactive decay is not the same as radioactive dating, but you need the decay to get the date. Radioactive isotopes each of a characteristic decay rate and if one knows the amount of such an isotope in an object when it was created, the level of radioactivity decreases predictably with age and one can calculate the age by knowing the decrease. Radioactive decay is good for a lot of other things too, just like the wind.
Definition of disintegration constant?
The disintegration constant is the fraction of the number of atoms of a radioactive nuclide which decay in unit time; is the symbol for the decay constant in the equation N = Noe^-t, where No is the initial number of atoms present, and N is the number of atoms present after some time (t).
If the half-life of a radioactive substance is 10 hours how long will it take for 50 percent of it to decay?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.
