What are the respective number of

\alpha

and

\beta^-

particles emitted in the following radioactive decay?

_{90}^{200}X \to \,_{82}^{172}Y

View answer and explanation

Correct option: A

7 and 6

Option A (7 and 6) is correct because the emission of an alpha particle reduces the mass number by 4 and the atomic number by 2, while the emission of a beta-minus particle increases the atomic number by 1 without changing the mass number.
