Thulium(II) chloride (
thulium dichloride), TmCl 2
Thulium(III) chloride (
thulium trichloride), TmCl 3
Kaynak: Thulium chloride Thulium(III) chloride or
thulium trichloride is the chemical compound composed of
thulium and chlorine with the formula TmCl 3.
Kaynak: Thulium(III) chloride Ytterbium has a density of 6.973 g/cm 3, which is significantly lower than those of the neighboring lanthanides,
thulium (9.32 g/cm 3) and

thulium oxide . Occurrence and production: File:Gadolinitas. jpg | Gadolinite
Kaynak: HolmiumThe primary decay product s before Er | 166 are element 67 (holmium ) isotopes, and the primary products after are element 69 (
thulium )

thulium in 1879. References : author Hans, Astrid Euler | year 1905 | title Per Theodor Cleve |
Kaynak: Per Teodor Clevecrust, neodymium is more abundant than gold and even
thulium (the least common naturally occurring lanthanide) is more abundant than iodine .
