If a radioactive isotope undergoes alpha decay it’s mass number changes by ?
Elis [28]

-4

Explanation:

If a radioactive isotope undergoes alpha decay, it's mass number will change by -4.

The mass number of a nuclei is the sum of its number of protons and neutrons.

An alpha particle is similar of a helium atom:

            ⁴₂He

The atom above is made up of:

  mass number = 4

  Atomic number = 2

  Number of protons = 2

  Number of neutrons = 2

 Number of electrons = 2

If a substance is undergoing radioactive decay, the mass number of the product will decrease by 4 and the atomic number will decrease by 2.

In nuclear equations, mass and atomic numbers are usually conserved.
