A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.

Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
The element samarium is named after Vasili Samarsky-Bykhovets, [10] and gadolinium is indirectly named (via the mineral gadolinite) after Johan Gadolin. [ 11 ] [ 12 ] Lecoq de Boisbaudran , who named the element gallium after his native land of France (from Latin Gallia meaning Gaul ) denied that the element's naming was for a pun on his own ...
After acidification he was able to distill the formed OsO 4. [49] He named it osmium after Greek osme meaning "a smell", because of the chlorine-like and slightly garlic-like smell of the volatile osmium tetroxide. [51] Discovery of the new elements was documented in a letter to the Royal Society on June 21, 1804. [46] [52]
In accordance with the proposal received from the discoverers, IUPAC officially named flerovium after Flerov Laboratory of Nuclear Reactions, not after Flyorov himself. [8] Flyorov is known for writing to Joseph Stalin in April 1942 and pointing out the silence in scientific journals in the field of nuclear fission in the United States, Great ...
Heavy metals – Variously-defined group of metals, on the base of their density, atomic number, or toxicity. Heavy atom – term used in computational chemistry to refer to any element other than hydrogen and helium. Minor actinides – Actinides found in significant quantities in nuclear fuel, other than U and Pu: Np, Am, Cm.
