Thulium, with the chemical symbol Tm, is the chemical element with the atomic number 69.
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
this elemnt has an atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.

The atomic number of thulium [note correct spelling] is 69.
Thulium--Tm, atomic number 69--is a silvery-white metal.
It is an element - a lanthanide metal - with atomic number 69.
An elements atomic number gives us its number of protons. Referencing the periodic table, we find the element with atomic number 69 is thulium. Thus, thulium has 69 protons.
Thulium has 100 neutrons because its atomic number is 69 and atomic mass is 168.93 so if we subtract atomic no. by atomic mass ie. 168.93-69 we get the value 100.
Thulium is an lanthanide element with atomic number 69.
168.93
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.

Thulium (Tm, atomic number 69) is a lustrous grey lanthanide metal that is ductile enough at room temperature to be sliced with a knife. Thulium is a scarce element, reacts readily with hot water but slowly with cold water, and has the ability to produce x-rays if it has been irradiated.
The sixty-ninth element in the periodic table is thulium (Tm). It is a rare earth metal with atomic number 69 and is named after the ancient city of Thule.
