The particle emitted in the decay of

{ }_{92}^{238} \mathrm{U}

{ }_{92}^{234} \mathrm{U}

View answer and explanation

Correct option: B

1 \alpha

and

2 \beta

Option B is correct because the mass number decreases by 4 (238 to 234) and the atomic number decreases by 2 (92 to 90) indicating the emission of an alpha particle, followed by two beta decays to restore the atomic number to 92.
