Polonium chemical properties:
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 physical properties

What else can I help you with?
Why are the properties of radium and polonium same?
Polonium and radium are radioactive chemical elements but they have not the same properties.
Is polonium similar to sulfur?
Polonium and sulfur are not similar. Polonium is a radioactive metal with toxic properties, while sulfur is a nonmetal element that is commonly found in nature. They have very different chemical and physical properties.
How is polonium a meatlloid?
Polonium is considered a metalloid because it exhibits properties of both metals and nonmetals. It can behave like a metal in terms of its electrical conductivity but also shows nonmetallic characteristics like brittleness. Polonium is found in the periodic table in the metalloid section due to its intermediate properties.
What is the electronegativity of polonium?
The Pauling electronegativity of polonium is 2.
What is the cost for one gram of polonium?
The cost of one gram of polonium is very high, estimated to be around $10,000,000 to $12,000,000 USD due to its rarity and radioactive properties.
Is polonium a metal non metal or metalloid?
Polonium is usually considered a poor metal, but can also be considered a metalloid.
What is the malleability of polonium?
We have not - very probable- data for the mechanical properties of polonium.
What is element of polonium?
Polonium is a natural radioactive element.
What happened after the discovery of polonium?
After the discovery of polonium by Marie Curie in 1898, it was further studied and its radioactive properties were better understood, leading to its use in various applications, such as in industry, medicine, and research. Polonium's role in radioactivity and nuclear physics became more prominent as scientists delved deeper into its properties and potential uses.
What are three unusual properties of polonium and radium?
These elements are: - radioactive - dangerous - rare - expensive
Is polonium metal sold like gold?
No, polonium is not commonly sold like gold. Polonium is a highly radioactive element and its access and use are strictly regulated due to its dangerous properties. It is mainly produced for scientific research and specialized industrial applications.
Is polonuim metal nonmetal metalloid?
Polonium has properties of both metals and non metals. It is hence considered to be a metalloid.
