Consider the nuclear reaction

\[ { }_{92} \mathrm{X}^{234}+\beta+\alpha \rightarrow \mathrm{Y}+\gamma+2 \beta^{+} \]

Y is

(a)${ }_{92} \mathrm{Y}^{238}$

(b)${ }_{91} \mathrm{Y}^{238}$

(c)${ }_{93} \mathrm{Y}^{236}$

(d)${ }_{94} \mathrm{Y}^{238}$

Answer

Answer: B ✓ checked by 4AB · confidence high

Explanation

Mass: 234 + 4 = 238. Charge: 92 − 1 + 2 = Z(Y) + 2, so Z = 91. Y is ²³⁸₉₁Y (b).
