State Nuclear decay equations.
Answers
Answer:
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons. The weak force is the mechanism that is responsible for beta decay.[1]
Radioactive decay is a stochastic (i.e. random) process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed.[2][3][4] However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as half-life. The half-lives of radioactive atoms have a huge range; from nearly instantaneous to far longer than the age of the universe.
Answer:
the radioactive decay of certain number of atoms ( mass) is exponentially in time. radioactive decay law n is n.e to the power - lambda t. the rate of nuclear decay is also measured in terms of half- lives. the half life is the amount of time it takes for a given isotope, to loose half of its radioactivity.
