Facts about Helium: Facts about the element Helium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Helium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Helium was first detected by French astronomer Pierre Janssen . It was discovered by Sir William Ramsey in 1895. Norman Lockyer and English chemist Edward Frankland named the element. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Helium is just one element that can be found.
