Im not sure, I will get back to you soon
<span>Answer is an </span>alpha emission<span>
Alpha decay is an emission of </span>₂⁴He <span>nucleus. If an
element undergoes an alpha decay, the mass of the daughter nucleus formed is reduced
by 4 compared
to mass of parent atom and atomic number is reduced by 2 compared to atomic number of parent
atom.
</span><span>Here parent atom is </span>Sm<span> which has
atomic number as 62 and mass number as 146. Since the emitted particle is a </span>₂⁴He<span> nucleus this is an alpha decay. Daughter atom will
have </span>146 - 4 = 142<span> <span>as mass number and </span></span>62 - 2 = 60<span> <span>as atomic number. Hence, daughter atom should
be </span></span>Nd<span> which has atomic number as 60.</span><span>
