"living organism. Tungsten interferes with molybdenum and copper metabolism, and is somewhat toxic to animal life. Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. With an ""estimated"" average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. The free element has the third-highest melting point and highest boiling point of any element. Rhenium resembles manganese chemically and is obtained as a by-product of molybdenum and copper ore's extraction and refinement. Rhenium"
"""tungsten"" (from the Swedish ""tung sten"", ""heavy stone"") is used in English, French, and many other languages as the name of the element, but not in the Nordic countries. ""Tungsten"" was the old Swedish name for the mineral scheelite. ""Wolfram"" (or ""volfram"") is used in most European (especially Germanic and Slavic) languages and is derived from the mineral wolframite, which is the origin of the chemical symbol W. The name ""wolframite"" is derived from German """"wolf rahm"""" (""wolf soot"" or ""wolf cream""), the name given to tungsten by Johan Gottschalk Wallerius in 1747. This, in turn, derives from """"lupi spuma"""","

"Period 7 element A period 7 element is one of the chemical elements in the seventh row (or ""period"") of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the same vertical columns. The seventh period contains 32 elements, tied for the most with period 6, beginning with francium and ending with oganesson, the heaviest element currently discovered."

In 1908, Japanese chemist Masataka Ogawa announced that he had discovered the 43rd element and named it ""nipponium"" (Np) after Japan (""Nippon"" in Japanese). However, recent analysis indicated the presence of rhenium (element 75), not element 43, although this reinterpretation has been questioned by Eric Scerri. The symbol Np was later used for the element neptunium, and the name ""nihonium"", also named after Japan, along with symbol Nh, was later used for element 113.

It is one of only two elements named after a person who was alive at the time of naming, the other being seaborgium; it is also the only element whose namesake is alive today. Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the nuclide Og have been detected. Although this allowed very little experimental characterization of its properties and possible compounds, theoretical calculations have resulted in many predictions,"
