Random decay refers to the spontaneous breakdown or disintegration of atomic nuclei without external influence, leading to the emission of radiation such as alpha, beta, or gamma particles. This process occurs unpredictably and is governed by the probabilistic nature of quantum mechanics, resulting in an exponential decay of radioactive isotopes over time.

Why is Radioactive decay is said to be random?

The underlying truth in radioactive decay is that on an individual basis, no unstable atom will have a predictable time until it will decay. We understand and characterize the decay of radionuclides on the basis of statistical analysis. Only by looking at a large number of atoms of a given isotope of a given element and counting the decay events over time can we quantify the decay rate. The term half-life is used to state (based on the statistics) when half of a given quantity of a substance will have undergone radioactive decay. Note that atoms are incredibly tiny things, and even if we have very tiny quantities of a given radioactive material, we'll have huge numbers of atoms of that material in the sample. The larger the number of atoms of material and the longer we count the decay events, the more accurate our half-life value will be. Having said all that, no one can predict when a given atom of any radionuclide will decay. Each is different, and that is the basis for the random nature of nuclear or radioactive decay.


Bacteria causes what decay?

All decay is bacterial (except when the term is used metaphorically, as in social decay).


Which is term used to describe the rate of a radioactive isotopes decay?

The term used to describe the rate of a radioactive isotope's decay is "decay constant," often denoted by the symbol λ (lambda). This constant is a probability measure that indicates the likelihood of decay of a nucleus per unit time, and it is related to the half-life of the isotope. The half-life is the time required for half of the radioactive atoms in a sample to decay.


Why do you think chemistry will not change the decay rate of an isotope?

Chemistry governs the interactions and properties of substances but does not influence nuclear processes such as radioactive decay. Radioactive decay rates are intrinsic to each isotope and are determined by the nucleus’s instability. This process is not affected by the chemical environment or external conditions.


What term used to describe rate of radioactive isotopes?

Half-life (in units of time).Half-Life is the rate of radioactive decay, measured in time. The half life gives the time it take for half of the radioactive atoms in a system to decay. Fore example, if you have 10 grams of carbon-14, it will take 5730 years for half of it to decay, giving you 5 grams. In another 5730 years, you'll have 2.5 grams left, etc...Isotopes decay at an exponential rate. A half-life is the time that half of the population of an isotope will decay. The measure is a statistical probability and is more accurate when a large population is observed. The term half-life is applied to describe a property of a given isotope (i.e. the half-life of Carbon 14 is 5730).half life
