What are polonium and radium?
Radium and polonium are natural radioactive chemical elements, discovered by Pierre and Marie Curie in 1898.
Who discovered random and polonium?

What did polonium and radium?
Polonium and radium are natural chemical elements, metals, solid, very radioactive.
Who isolated polonium and radium?

Henri becquerel discovered radium and polonium?
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
Are metals radioactive elements?
No. All elements with atomic number greater than 83 are radioactive, including some metals such as polonium, uranium, etc. But there are radioactive isotopes of most metals on the periodic table but are very rare and sometimes must be produced in reactor or particle accelerator.
What is polonium and radium elements?
Polonium and radium are two natural chemical elements, highly radioactive, solid, metals, rare, expensive, dangerous, with some useful applications etc.
Is polonium more radioactive than uranium?
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. They are two natural elements, metals, extremely radioactive.
What family of metals are all radioactive?
Actinoids, and generally all the elements from polonium (atomic number 84) to ununoctium (atomic number 118).
What is the radioactive alkali metal?
Francium name by the Curies after france. Yes it is rare and radioactive.
How does polonium react with chemicals?
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.
What element family does rhodium belong to?
Polonium is in the chalcogen family but is commonly said as the oxygen family. - Polonium is in the 16th group of the periodic table - Polonium is a metalloid - Polonium is a natural radioactive chemical element Group 16 (chalcogens) in the Mendeleev table of elements; the chalcogens are: O, S, Se, Te Po.
