A radioactive element

{}_{92}^{238}U

undergoes successive radioactive decay and decays into

{}_{82}^{206}Pb

.The number of

\alpha\,\, \mathrm{ }and\mathrm{ }\,\,\beta

particles emitted respectively are:

View answer and explanation

Correct option: C

8 and 6

Option C (8 and 6) is correct because the number of alpha and beta particles emitted can be determined by balancing the mass number and atomic number in the nuclear decay equation.
