Fluorine
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
Fluorine was first isolated by Henri Moissan in 1886.
Fluorine
Fluorine was isolated for the first time by Henri Moissan in 1886.
1886
French chemist Henri Moissan first isolated elemental fluorine in 1886. To recognise the "great services rendered by him in his investigation and isolation of the element fluorine", he received the Nobel Prize in chemistry in 1906.
Chlorine was isolated before fluorine because fluorine is the most reactive element and can react to the most other elements, making it hard to isolate and separate from other elements.
It might be said that Karl Scheele along with many others, independently discovered Fluorine at different times, but it was in 1886 when Henri Moisson first successfully isolated elemental Fluorine.
