219/86Rn>215/84Po+a

The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle. In one to two sentences, explain whether or not the reaction is balanced.

The nuclear equation is not balanced because there is a difference in the number of nucleons on both sides of the equation.

To determine whether or not the reaction is balanced, we need to check if the number of atoms of each element is the same on both sides of the equation. In this case, the equation is not balanced because the number of atoms of each element is different on both sides.
