Polonium-218 has 84 protons, 84 electrons and 134 neutrons.
Radon-222 has 86 protons, 86 electrons and 136 neutrons.
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
In the case of Rn-222, which is the "isotope of concern" because it occurs naturally, it decays as follows: 222Rn => 218Po + He+2 In this equation, we see the radon isotope Rn-222 emit an alpha particle (the helium nucleus) and undergo a transformation to become the polonium isotope, Po-218.
The isotope radon-198 will alpha decay to polonium-194 as shown here: 86198Rn => 24He + 84194Po The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
Radon is a colorless, odorless radioactive gas that can seep into homes and buildings from the ground, potentially causing lung cancer if inhaled in high concentrations. Polonium is a radioactive element that is toxic and can be harmful if ingested or inhaled. Both substances can pose health risks if proper precautions are not taken to reduce exposure.
The electron configuration of polonium is: [Xe]6s24f145d106p4.

Radium itself continues to decay into radon, bismuth, polonium, lead, or thallium.
A two-dimensional model of radon can be represented by a circle or sphere to indicate the central nucleus with 86 protons and a corresponding number of neutrons. Electrons can be shown orbiting around the nucleus at varying distances in different energy levels. The model should reflect the electron configuration of radon, which is 2,8,18,32,18,8.
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
