What is the chemical symbol of polonium?
Polonium with the atomic number 84 is in the group 16 and period 6 of the periodic table of Mendeleev. 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.
What kind of bond is formed between nitrogen and polonium?
A covalent bond is typically formed between nitrogen and polonium. In this type of bond, the atoms share electrons to achieve a stable electron configuration. Due to the large size and differences in electronegativity between nitrogen and polonium, the bond may have some degree of ionic character as well.
How does polonium react with chemicals?
Polonium is a highly reactive metal that readily reacts with nonmetals to form compounds. It can react with oxygen to form polonium oxides and other compounds. Due to its intense radioactivity, handling and studying polonium is extremely challenging.
What element is most commonly found in a compound with polonium?
Polonium with the atomic number 84 is in the group 16 and period 6 of the periodic table of Mendeleev. 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. Polonium is considered generally as a metal but some chemists consider Po as a metalloid.
What is the formula for polonium oxide?
Two polonium oxides are known: PoO2 and PoO3.

Why is oxygen more reactive compared to polonium?
The electronegativity of oxygen is much higher than that of polonium, even though their valence electron configurations are superficially the same, because an oxygen atom is much smaller than a polonium atom, so that accepted additional electrons are much closer to the electrically attractive nucleus of an oxygen atom than of a polonium atom.
