What is thulium?
It is an element - a lanthanide metal - with atomic number 69.
What element does have 69 protons?
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.
What element has 59 protons?
That would be Thulium, atomic symbol Tm.
What element has a atomic mass of 39.9?
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).
What are thulium's characteristics?
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.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
