To What Element Does Polonium 208 Atomic Number 84 Decay When It Emits an Alpha Particle?

Polonium-208 is a radioactive isotope of polonium with an atomic number of 84 and a mass number of 208. It undergoes alpha decay, emitting an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. When polonium-208 decays, it loses two protons and two neutrons, resulting in the formation of a new element with an atomic number of 82 and a mass number of 206.

The element that polonium-208 decays into is lead-206.
