A radioactive decay is illustrated. Which radioactive emission is a product of this decay? A)Alpha

B)beta

C)gamma

D)positron

The radioactive decay is shown in the image attached to this answer

Alpha

Explanation:

An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.

If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.
