41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
The -ine suffix is used only for the halogens, with chlorine being named first, and the others being named to match. The suffix -gen is used for three other nonmetals forming diatomic molecules (hydrogen, nitrogen, and oxygen). Suffixes were used more inconsistently before 1784, with tungsten (discovered 1783) the last element discovered whose ...
Fluorine's name comes from the Latin word fluere, meaning "to flow", because it was derived from the mineral fluorite, which was used as a flux in metalworking. Chlorine's name comes from the Greek word chloros, meaning "greenish-yellow". Bromine's name comes from the Greek word bromos, meaning "stench".

None of the teens were publically named by police because they are all minors. They all turned themselves in last month and were taken to Chicago’s Cook County Juvenile Detention Center.
Radical fluorique appears on the list of elements in Lavoisier's Traité Élémentaire de Chimie from 1789, but radical muriatique also appears instead of chlorine. [75] André-Marie Ampère again predicted in 1810 that hydrofluoric acid contained an element analogous to chlorine, and between 1812 and 1886 many researchers tried to obtain it.
