WebJan 30, 2024 · Each shell can only hold certain number of electrons. K shell can have 2, L can have 8 , M can have 18 electrons and so on. Lithium has three electrons: two go to K shell and the remaining one goes to the L shell. Its electronic configuration is K (2), L (1) Fluorine has nine electrons: two go to K shell and the remaining seven go to the L shell. WebJan 11, 2024 · Quantum mechanics sets no limit as to how many energy levels exist, but no more than 7 principal energy levels are needed to describe all the electrons of all the known atoms. Each energy level can have as many sub-levels as the principal quantum number, as discussed above, and each sub-level is identified by a letter. did lincoln win a second term
