Disintegration energy?is the?energy?released during radioactive decay. Nuclear physics involves the study of many nuclear reactions, where one atom or particle turns into another, or where particles collide creating new ones.
69) The disintegration energy is
Answer is:
the difference between the initial mass energy and the total mass energy of the decay products

Related Atoms and Nuclei MCQ with Answers
Answer is:
nuclei of a given species transform by giving out??or?or??rays
Explanation:
Radioactive?decay, also known as nuclear decay orradioactivity, is the process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles, gamma rays and conversion electrons. A material that spontaneously emits such radiation is consideredradioactive.
Answer is:
He nuclei
Explanation:
Alpha?rays are actually high speed?particles. Early researchers tended to refer to any form of energetic?radiation?as?rays, and the term is still used. An?alpha particleis made up of two protons and two neutrons, all held together by the same strong nuclear force that binds the nucleus of any atom.
Answer is:
electrons and electromagnetic radiation of wavelengths shorter than X-rays
Explanation:
??-rays and???-rays are respectively electrons and electromagnetic radiation of wavelengths shorter than X-rays
Answer is:
N(t)=N(0)e?\lambda t
Explanation:
Radioactivity:?Law of Radioactive Decay.?Radioactivity?is the phenomenon exhibited by the nuclei of an atom as a result of?nuclear?instability. It is a process by which the nucleus of an unstable atom loses energy by emitting?radiation.Radioactivity?was discovered by Henry Becquerel completely by accident.
