The number of beta particles emitted by a radioactive substance is...

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 :

Options

  1. AIsotope of parent
  2. BIsobar of parent
  3. CIsomer of parent
  4. DIsotone of parent

Correct answer

A. Isotope of parent

Step-by-step solution

ZA⟶αZZ−2YA−4⟶2βZA−4\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.
