Polonium, named in honor of Poland, was the first element discovered by Pierre and Marie Curie in 1898.
Polonium and radium doesn't affect history.
The discovery (not invention) of polonium and radium didn't changed the history.
Polonium is a reactive metal but being very radioactive, dangerous, scarce and expensive the chemistry of Po was not intensively studied.Some compounds of polonium are: PoO, PoO2, PoO3, PoH2, halides as PoX2, PoX4, PoX6 and the strange class of polonides (compounds of polonium with other metals). The Pauling electronegativity is 2. Possible valences are: 2, 4, 5, 6, -2.
