The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.Ok so I'll take you through some interesting facts and data about Thulium (That most people don't know).
Thulium Overview
Atomic Symbol
Tm (Thulium)
Description
Soft, malleable, ductile, silvery metal
State at 20 °C
Solid
Sources
Found with other rare earths in the minerals gadolinite, euxenite, xenotime, and monazite. Monazite is often 50% rare earth by weight and 0.007% thulium.

Uses
Radioactive thulium is used to power portable x-ray machines, eliminating the need for electrical equipment.
