Is nuclide and isotope the same?

Isotope and nuclide are closely related terms. When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Nuclide is a more general term, referring to a nuclear species that may or may not be isotopes of a single element.

Do atoms exist forever?

Ultimately, even these stable atoms have a limit imposed by the lifetime of proton (>1025 years). Remember, though, that the best estimate of the present age of the universe is the much smaller number of 1010 years, so for all practical purposes, atoms are forever.

Does radioactive decay give off heat?

Decay heat is the heat released as a result of radioactive decay. This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms.

Do atoms have intelligence?

A measure of intelligence of an atom can therefore be its valence since it gives a measure of how many other atoms it can combine with, resulting in a variety of molecules. But a better measure of an atom’s intelligence is also its ability to form chains or repeated links thereby forming complex compounds.

Do atoms have memory?

One bit of digital information can now be successfully stored in an individual atom, according to a study just published in Nature. Current commercially-available magnetic memory devices require approximately one million atoms to do the same.

What is a radioisotope?

The radioisotope is a radioactive element that emits radioactive rays. Radioactive has an important role in complementing human needs in various fields. One of them is in medicine and health. The use of radioactive isotopes in the medical field are for radiodiagnostic and radiotherapy that are also called as nuclear medicine.

Which of the following is an example of radioactive isotope?

Here, we will choose the examples of radioactive isotopes of most popular elements like hydrogen, carbon, oxygen, Nitrogen, Iodine, Potassium, uranium, etc. Some of the elements in the periodic table can spontaneously emit radioactive radiations like alpha ray, gamma ray and beta ray. Such elements are the radioactive elements.

What is the half-life of a radioactive isotope?

Some significant naturally occurring radioactive isotopes isotope half-life (years, unless noted) 3 H 12.32 14 C 5,700 50 V >2.1 × 10 17
