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, with the chemical symbol Tm, is the chemical element with the atomic number 69.
The average atomic mass for titanium is 47.867.
Thulium--Tm, atomic number 69--is a silvery-white metal.
The average atomic mass of Lithium (Li) is 6.941.
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
Average atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundances. Atomic mass refers to the mass of a single atom of a specific isotope of an element.
Atomic mass refers to the mass of an individual atom of a specific element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature. Average atomic mass is usually listed on the periodic table, while atomic mass is specific to a single isotope.
Carbon has an average atomic mass of about 12.
Atomic Mass is the number of protons and neutrons in an atom.
The Atomic Mass of krypton is 83.80(1) if you round 84
