All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.

When bismuth-214 emits a positron, it undergoes beta-plus decay to produce polonium-214. This decay process involves the conversion of a proton into a neutron, releasing a positron and a neutrino.

Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.

Polonium is a solid, man-made, radioactive poor metal.
Atomic number becomes two units less and atomic mass four units less. Bismuth is the answer.
When bismuth-214 emits a positron, it undergoes beta-plus decay to produce polonium-214. This decay process involves the conversion of a proton into a neutron, releasing a positron and a neutrino.
Polonium, with an atomic number of 84, loses electrons to reach a stable octet configuration. It loses electrons and undergoes alpha decay to achieve a more stable state.

Polonium-210 decay to lead-206.
Polonium glowing green is due to a phenomenon called radioluminescence. When polonium undergoes radioactive decay, it emits alpha particles that collide with a phosphor material in the surroundings. This collision causes the phosphor to emit light, which can manifest as a green glow when observed.
Polonium-210 is an alpha emitter with a half-life of about 138 days. Its decay rate, or how fast it emits alpha particles, is a constant process determined by its decay constant, which is approximately 5.3 x 10^−9 per second.
