Question 340: Atoms & Nuclei

Question

A radioactive element $_{92}^{242}$X emits two $\alpha$-particles, one electron and two positrons. The product nucleus is represented by $_{\mathrm{P}}^{234}$Y. The value of P is __________.

Accepted Answer

${ }_{92}^{242} \mathrm{X} \stackrel{{ }^{2 \alpha}}{\longrightarrow}{ }_{88}^{234} \mathrm{~A} \stackrel{\mathrm{e}^{-}}{\longrightarrow}{ }_{89}^{234} \mathrm{~B} \stackrel{2 \mathrm{e}^{+}}{\longrightarrow}{ }_{87}^{234} \mathrm{Y}$
So, $P=87$
