The rate of decay of a radioactive element is measured by its what?
The rate of decay of a radioactive element is measured by its half-life, which is the time it takes for half of a sample of the element to decay. This measurement is used to determine the stability or instability of the element and to predict its rate of decay over time.
What term indicates the process in which unstable nuclei releases radiation?
Radioactive decay is the process in which unstable nuclei release radiation in the form of alpha particles, beta particles, or gamma rays.
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
What is a radioactive element's half-life?
The time it takes for a half of the element to decay. In Example: Technetium-99 has a half life of 6 hours. If you begin with a sample of 100g, then after 6 hours you will have 50 grams, at 12 hours you will have 25 grams and so on; however it will NEVER reach 0 (it will remain in exponentially small ammounts because of the asymptote in the graph). This specific exponential decay is shown by the equation y=100(0.5)((1/6)x)
Why is curium 242 not suitable for use in smoke detectors?
Curium-242 is not suitable for use in smoke detectors because it is a radioactive isotope that emits high-energy alpha particles, which can be harmful to human health if exposed in close proximity over extended periods of time. Additionally, curium-242 has a long half-life, making it unsuitable for the short-term detection requirements of smoke detectors.
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 is the term radioactive decay used to describe the phenomenon?
The term "radioactive decay" is used because it refers to the process by which unstable atomic nuclei lose energy by emitting radiation. This process results in the transformation of the original element into a different element or isotope. The word "decay" indicates the gradual decrease or disintegration of the unstable nucleus over time.
The rate of decay of a radioactive element is measured by its what?
The rate of decay of a radioactive element is measured by its half-life, which is the time it takes for half of a sample of the element to decay. This measurement is used to determine the stability or instability of the element and to predict its rate of decay over time.
What is the difference between and radioactive and stable isotope?
Radioactive isotopes emit radiation in the form of alpha, beta, positron or gamma rays to become a stable isotope of any given particular element. This is caused by the instability of the nucleus of the atom. The stabilising process in which unstable atoms undergo is known as radioactive decay. Isotopes that are stable do not emit radiation. For example; Carbon-12 is stable and carbon-14 is radioactive.
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
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
What term indicates the process in which unstable nuclide release radiation?
If it is related to Nuclear studies, then the answer would be fusion.
When do the decay series end?
When the element is stable. (apex)
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.
What does the half life of a radioisotopes indicate?
The half life of a radioisotope indicates the rate of decay for a radioactive sample
What term indicates the process in which unstable nuclei releases radiation?
Radioactive decay is the process in which unstable nuclei release radiation in the form of alpha particles, beta particles, or gamma rays.
A general term for any isotope of any element?
Nuclide
