Applications of Radioactive Elements Uranium-235: Used in nuclear power plants, where its decay initiates a chain reaction that releases energy used to generate electricity. U-235 undergoes alpha decay and releases neutrons that continue the reaction. ...
Question: To determine the age of rocks, the decay of which radioactive element(s) can be used? a) carbon-14 b) phosphorus-40, uranium-234, and/or rubidium-87 c) uranium-240, uranium-238, rubidium-87, and/or potassium-40 d) ca...
Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.
Natural sources of nuclear decay can be found in the soil, from cosmic radiation that comes from space, and from the sun. Radioactive elements like radon also occur naturally on Earth, and other types of radioactive particles can also be ingested through contaminated food. Artificial sources of...
After the initial flash has faded, the total luminosity of the remnant is provided by the release of energy from the natural decay ofradioactive elementsproduced in the explosion. Each element emits energy at some characteristic wavelengths as it decays, providing insight into thechemical composition...

The naturally occurring radioactive isotopes of the heaviest elements fall into chains of successive disintegrations, or decays, and all the species in one chain constitute a radioactive family, or radioactive decay series. Three of these series include most of the naturally radioactive elements of...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
The radioactive decay rate of a radioactive element is found to be 10^(3) disintegration s^(-1) at a certain time. If the half-life of the element is 1s, the
