Yes they need to be approved by the IUPAC - The International Union of Pure and Applied Chemists. This is for standardisation purposes. Usually elements are named after the place or person who discovered/isolated them.
Yes. IUPAC - The International Union of Pure and Applied Chemists usually approve these.
The elements that are newly discovered or are radioactive and found in traces are usually named according to a system of nomenclature based on their atomic nos.Eg. element 243 (if discovered, some day) will be named as biquadtrium (Bqt) which is NOT the proper symbol/name for the element.
People say they have made the element unahexium but hasn't been confirmed and even if there has been and element confirmed its only stable for a few milliseconds before it decays into more stable elements.
People decide on who gets the credit of discovering the new element, and then who gets the honor of naming it. Often times they name the new element after a place, country, scientist, or myths, etc.
Cartier named the newly discovered land "Canada" after the Iroquois word "kanata," meaning village or settlement.
Yes, the element neon is named after the Greek word "neos," meaning new. This name was chosen because neon was a newly discovered element at the time of its naming.
Who ever discovers it.
The name of the natural radioactive chemical element uranium is derived from the name of the planet Uranus. Uranium was discovered (as an oxide) by Martin Heinrich Klaproth in 1789.
It is named after the planet ' Uranus'. The planet Uranus, together with Saturn , Jupiter et. al are from Classical Greece. From Classical Greek Mythology, Uranus, was the personification of the 'Sky', and was one of Greek primordial deities.
The element was discovered by (insert name of scientist or researcher).
The name of the artificial chemical element darmstadtium is derived from the name of the town Darmstadt (Germany) where this element was discovered.
Nowadays, UIPAC decides whether a name given to an element will become the standard or not. Generally, they have been giving names based on the element's number. A science teacher of mine tells me that this was originally to settle disputes between groups of people who thought they had discovered an element "first".
