POLONIUM (REVISED) Polonium was discovered in 1898 by Polish-French physicist Marie Curie (1867-1934) and her husband, Pierre (1859-1906). They were looking for the source of radioactivity in a naturally occurring ore called pitchblende. Radioactivity is the process by which materials give off energy and change into new materials. 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.

Group 5 element Group 4 is a group of elements in the periodic table. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.

- When it is mixed or alloyed with beryllium, polonium can be a neutron source: beryllium releases a neutron upon absorption of an alpha particle that is supplied by 210 Po. It has been used in this capacity as a neutron trigger or initiator for nuclear weapons.Other uses include.hen it is mixed or alloyed with beryllium, polonium can be a neutron source: beryllium releases a neutron upon absorption of an alpha particle that is supplied by 210 Po.

Polonium: the essentials Polonium was the first element discovered by Marie Sklodowska Curie in 1898, while seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia.It required several tonnes of pitchblende to produce very small amounts of polonium.olonium is produced through decay of the small quantities of the bismuth isotope 210 Bi present in pitchblende (uranite, largely UO 2). However the quantities are very small. Uranium ores might contain about 0.0001 g of polonium in a tonne of ore.

Carbon family Photo by: Jeffrey Rasmussen. The carbon family consists of the five elements that make up Group 14 of the periodic table: carbon, silicon, germanium, tin, and lead. The family is particularly interesting because it consists of one nonmetal (carbon), two metals (tin and lead), and two metalloids (silicon and germanium).

Polonium Element Facts Polonium, also called Radium F, was the first element discovered by Marie S. Curie. She discovered it in 1898 while investigating radioactivity in pitchblende (uranium oxide). The element is named after Poland, the country of Curie's birth.olonium is a rare, silvery-gray, radioactive low-melting metalloid. Polonium readily reacts with dilute acids, but only slightly with alkalis. All of its isotopes are radioactive. 210 Po emits a blue glow, as the air around it is excited by the decay products.

General Chemistry/Chemistries of Various Elements/Group 14 Group 14 (IVA) consists of carbon, silicon, germanium, tin, and lead. Carbon is a non-metal, silicon and germanium are metalloids, and tin and lead are metals. With 4 valence shell electrons, elements of the carbon family tend to form covalent compounds. With increasing mass and atomic radius these elements become increasingly metallic and have lower melting and boiling points. Group 14 elements form gaseous hydrogen compounds with difficulty.

Backgrounder on Polonium-210 Polonium-210 is a radioactive isotope that occurs in small amounts in nature and can be made in a nuclear reactor. It has limited uses, mainly in static eliminators. In recent years, polonium made the news because of its use as a poison.Polonium was blamed for the Nov. 23, 2006, death in London of the Russian Alexander Litvinenko. It has also been mentioned as a possible cause of Yassar Arafat's death.olonium-210 as a poison. The chance of someone acquiring a lethal dose of polonium-210 is very small. Both the form and amount of radiation in exempt sources mean they would pose no health problem if ingested.

Chalcogen The four lightest chalcogens (oxygen, sulfur, selenium, and tellurium) are all primordial elements on Earth. Sulfur and oxygen occur as constituent copper ores and selenium and tellurium occur in small traces in such ores. Polonium forms naturally after the decay of other elements, even though it is not primordial.

- The periodic table is designed so elements in the vertical columns (groups) have the most similarities in chemical and physical properties. So, Iodine is most similar to the … other non-metals in the Halogen family, such as Fluorine, Chlorine, Bromine, and Astatine.9 people found this useful.agnesium, calcium, strontium, barium and radium have similar  properties to beryllium.   All the elements in group two of the periodic table have the same  or similar p … roperties. This is because they have the same number of  electrons in their outermost shell.
