Half-life
It's called the half-life.
its called the half-life and it is different for each nuclide.
The decay product ratio is the ratio of the amount of a specific decay product to the amount of the parent isotope in a radioactive decay chain. It is used to determine the relative contribution of different decay pathways in the decay of a radioactive substance.
Exponential growth is when the amount of something is increasing, and exponential decay is when the amount of something is decreasing.
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
The half-life
radioactive decay
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
It does not usually involve the atom's electrons, except for a type of decay called K capture. But the beta particles ejected in what is called beta decay are either electrons or positrons.
