Question

219 over 86 Rn→215 over 84Po+αThe 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.

Answer 1

Step-by-step explanation:

The nuclear reaction that we have to work with is the transmutation of radon into polonium and an alpha particle.

An alpha particle consist of two protons and two neutrons bound together in a particle. Since it has 2 protons and 2 neutrons the atomic number of this particle is 2 and the atomic mass is 4. We can add those numbers into our equation.

So if we add the atomic mass and the atomic number of the polonium to the atomic number and mass of this particle, we will see that we get the same atomic number and atomic mass as radon.

The equation is balanced.

Answer: The equation is balanced.
