Use the equation to complete the activity.

219 86Rn→215 84Po+α

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 reaction is not balanced because the total number of protons and neutrons is not the same on both sides of the equation.

The reaction is not balanced because the atomic numbers (proton numbers) on both sides of the equation are different.

To determine if the reaction is balanced, you need to ensure that the total number of protons and neutrons on both sides of the equation is the same. In this case, the reaction is not balanced because the mass numbers do not match on both sides.
