Answer:
All radon isotopes have 86 protons (Z=86).
But radon-222 has 136 neutrons (86 + 136 = 222).
Whereas radon- 220 has only 134 neutrons (86 + 134 = 220).
The chemical symbol for radon is Rn, and the mass number is usually placed either after the symbol (Rn-222) or to the left and above it (222Rn).
