Question

Find the resulting isotope when Polonium-218 decays, it emits a beta particle, followed by an $\alpha$-particle ?

• A. bismuth-214
• B. bismuth-212
• C. lead-214
• D. astatine-212
• E. lead-222

Answer 1

The correct option is A bismuth-214

The reaction can be given as:

${}_{84}P{o}^{218}{\to }_{85}A{t}^{218}{+}_{-1}{\beta }^0+E$

${}_{85}A{t}^{218}{\to }_{83}B{i}^{214}{+}_{2}H{e}^4+E$
