The number of beta particles emitted by a radioactive substance is twice the number of alpha particles emitted by it. The resulting daughter is an :
Isotope of parent
Isobar of parent
Isomer of parent
Isotone of parent
Solution
$\quad \mathrm{Z}^{\mathrm{A}} \stackrel{\alpha}{\longrightarrow} \mathrm{Z}_{\mathrm{Z}-2} \mathrm{Y}^{\mathrm{A}-4} \stackrel{2 \beta}{\longrightarrow} \mathrm{Z}^{\mathrm{A}-4}$
As the resulting daughter and parent nucleus has same atomic number. So they are isotope.
