Question

Radon decays to polonium by emitting alpha particles as shown by the following equation: $_{y}^{x} R n \to_{86}^{218} P o + α$ . What are the values of x and y?

Open in App

Solution

$_{x} {R n}^{y} \to_{86} {P o}^{218} +_{2} α^{4} x = 86 + 2 = 88 y = 218 + 4 = 222 S o, x = 88 a n d y = 222$

Q. Initially, the nucleus of

Radium - 226

is at rest. It decays by emitting an

α -

particle, and thus the nucleus of

Radon

is created. The released energy during the decay is
