Son nom dérive du grec « … 32 radioactive isotopes of thulium have been produced, with atomic masses ranging from 146 to 177. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy.
