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.
How many neutrons would it have if it had 11 neutrons? 11.
There are 71 neutrons in tellurium-123
12 neutrons are in sodium (Na).
there are 66 protons & 97 neutrons
Carbon 12 has 6 neutrons
69 protons, 69 electrons Thulium-169 isotope has 100 neutrons
Thulium (Tm) has an atomic number of 69, which means it has 69 protons. The most stable isotope of thulium, Tm-169, has 100 neutrons. Therefore, Tm typically has 100 neutrons in its most common isotope.
There are 69 protons and electrons, along with 100 neutrons. =)
Thulium has 79 shells.

The symbol for tantalum is Ta.
Thulium belongs to the Lanthanide family. Thulium is a silvery metal, so soft it can be cut with a knife. Thulium is stable in air, but reacts slowly with water, and rapidly with acids.
Thulium, with the chemical symbol Tm, is the chemical element with the atomic number 69.
Thulium has an electronic configuration of [Xe] 4f136s2 You could count either 2 or 15. The concept of valence electrons is almost meaningless when applied to the lanthanides. Thulium is a typical member of these and has one common oxidation state, +3
The element with 45 protons is Rhodium which has the chemical symbol Rh. Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 shells with 1 electron in the outer shell.
Thulium is an lanthanide element with atomic number 69.
