Question

isotopes of polonium

Answer 1

Polonium-208
Polonium-214
Polonium-209
Polonium-218
Polonium-212

Answer 2

Polonium (84Po) has 33 isotopes, all of which are radioactive, with between 186 and 227 nucleons. 210Po with a half-life of 138.376 days has the longest half-life of naturally occurring polonium. 209Po with a half-life of 125 years has the longest half-life of allisotopes of polonium. 209Po and 208Po (half-life 2.9 years) can be made through the alpha, proton, or deuteron bombardment of lead orbismuth in a cyclotron.
