Difference between Atomic Number 69 and Thulium

ATOMIC NUMBER 69 vs THULIUM: NOUN

A soft silvery metallic element of the rare earth group; isotope 170 emits X-rays and is used in small portable X-ray machines; it occurs in monazite and apatite and xenotime

A metallic chemical element (symbol Tm) with an atomic number of 69.
A rare metallic element of uncertain properties and identity, said to have been found in the mineral gadolinite.
A supposed element found in the mineral gadolinite. Its properties have not been ascertained, and its existence is doubtful.
The name was given in 1879, by Cleve, to a supposed new element present in the compounds of Mosandu' s erbium extracted from gadolinite. The evidence of its existence was found in an examination of the absorption-spectra of products of the fractionation of erbium salt solutions, but it is very doubtful whether the separation is complete and whether thulium is to be considered as a distinct and single element.
A bright, soft, silvery rare-earth metal obtained commercially from monazite, having an x-ray emitting isotope that is used in small portable medical x-ray units. Atomic number 69; atomic weight 168.934; melting point 1,545°C; boiling point 1,950°C; specific gravity 9.321 (at 25°C); valence 2, 3. : Periodic Table.
