Polonium is the heaviest element in the chalcogen family. It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium. SYMBOL Po ATOMIC...
Polonium (Po or Element 84) is one of the radioactive elements discovered by Marie and Pierre Curie. This rare element has no stable isotopes. It's found in uranium ores and cigarette smoke and also occurs as a decay product of heavier elements. Although there aren't many applications for ...

The first two of these elements— polonium and radium—were discovered by Marie Curie (1867-1934) and Pierre Curie (1859-1906). The third, actinium, was discovered in 1899 by a close friend of the Curies, French chemist André Debierne (1874-1949). Debierne suggested the name actinium ...
an average individual will receive a dose of about 120 µSv per year from ingestion and inhalation of decay products of uranium, such as radium-226 and its progeny in water, radon-222 in homes and polonium-210 in cigarette smoke. Nevertheless, because of the differences in diets, as well...

Element 116 was called eka-polonium, using Mendeleev's naming convention for unverified elements, or ununhexium (Uuh), usingthe IUPACnaming convention. Once a new element's synthesis is verified, the discoverers get the right to give it a name. The Dubna group wanted to name element 116 ...
Luckily for humans, most of the toxic elements on the planet exist in very low quantities in nature. This said, some elements are concentrated specifically because of their toxic properties. Answer and Explanation:1 The most toxic element ispolonium. It is estimated that, if ingested, as little...
