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.
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.
These elements doesn't have effects on daily life.
The neutrons aren't really relevant, since we don't know what the mass of the radium nucleus was and the element is determined strictly by the number of protons anyway. Radium has an atomic number of 88; losing 4 protons would make the atomic number 84, which is polonium. (This is probably really a two-step process: radium -> radon -> polonium, where each step is an alpha decay.)
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.

Polonium and especially radon contribute to the natural environmental radioactivity.
radon and polonium
Radon has 86 protons.
Radium itself continues to decay into radon, bismuth, polonium, lead, or thallium.

The number of electrons in the shells around a radon nucleus are: 2, 8, 18, 32, 18 and 8.
