Berzelius privately named the putative element "thorium" in 1817 [98] and its supposed oxide "thorina" after Thor, the Norse god of thunder. [99] In 1824, after more deposits of the same mineral in Vest-Agder, Norway, were discovered, he retracted his findings, as the mineral (later named xenotime) proved to be mostly yttrium orthophosphate.
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 ...
Thorium was discovered in 1828 by the Norwegian amateur mineralogist Morten Thrane Esmark and identified by the Swedish chemist Jöns Jacob Berzelius, who named it after Thor, the Norse god of thunder and war, because of its power. Its first applications were developed in the late 19th century.
32 of these have names tied to the Earth and the other 10 have names connected to bodies in the Solar System. The first tables below list the terrestrial locations (excluding the entire Earth itself, taken as a whole) and the last table lists astronomical objects which the chemical elements are named after.

Dubnium and Moscovium were named after Russia's Dubna [23] and Moscow cities. Several places in Scandinavia have elements named after them. Yttrium, terbium, erbium, and ytterbium are all named for the Swedish village of Ytterby, where their ores were first found. [24] Hafnium is named after Hafnia, the Latin name for Danish capital Copenhagen ...
This named isotope later became the official name for element 86 in 1923. T: Tritium: 1: From the Greek tritos. Name given to 3 H. Th: Thorium: 90: After Thor. Name restricted at one time to 232 Th, an isotope of thorium. This named isotope later became the official name for element 90. ThA: Thorium A: 84

An international committee decided in 1992 that the Berkeley and Dubna laboratories should share credit for the discovery. An element naming controversy erupted and as a result IUPAC adopted unnilhexium (Unh) as a temporary systematic element name. In 1994, a committee of IUPAC adopted a rule that no element can be named after a living person. [15]
