Question

Why is there an inverse relationship between the alpha decay half-life and the decay energy?

Answer 1

It is bcoz the relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ.

Answer 2

Hello mate here is your answer.

Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleusemits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons. It has a charge of +2 e and a mass of 4 u. For example, uranium-238 decays to form thorium-234. Alpha particles have a charge+2 e, but as a nuclear equation describes a nuclear reaction without considering the electrons – a convention that does not imply that the nuclei necessarily occur in neutral atoms – the charge is not usually shown.

Hope it helps you.
