The alpha decay of a radioactive nuclide (X) emits a He-4 nucleus and produces an isotope of Superscript 235 subscript 92 upper U.. What is X?

Thus X is Plutonium

Explanation:

Alpha Decay: In this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. The mass number is reduced by 4 units and atomic number is reduced by 2 units.

General representation of alpha decay :

where Z = atomic number

A= mass number

X and Y = atomic symbol of elements

Thus

Thus X is Plutonium with atomic number 94 and mass number 239
