if an atom of polonium-218 were to undergo alpha emission, followed by two beta emissions, which nuclide would result? lead-214

tia_tia [17]

Po, (218, 84) - Alpha Particle (4, 2) = (218 - 4, 84 - 2) = <span>(214 , 82)</span>

(214 , 82) - 2Beta = (214, 82 - 2*(-1)) = (214 , 84)

Polonium has atomic number of 84.

So answer = Polonium-214
