Question

Which type of radioactive decay does the equation model?

a) "Alpha decay"
b) "Beta decay"
c) "Gamma decay"
d) "Nuclear fission"

Answer 1

The equation given models alpha decay. Alpha decay is a common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus).

Step-by-step explanation:

The equation given models alpha decay. Alpha decay is a common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). The equation 4XN AYN + He represents alpha decay, where the parent nucleus emits an alpha particle to produce a daughter nucleus with a reduced atomic number and mass number.
