If ‘K’ and ‘L’ shells of an atom are completely filled, then what would be the total number of electrons in an atom?

If ‘K’ and ‘L’ shells of an atom are entirely filled, then the total number of electrons in that will be 10.

According to the Bohr-Bury scheme, the maximum number of electrons present in a shell = 2n². Where "n" is the orbit number. ‘According to this rule, 'K’ and 'L’ shells of an atom can have a maximum of 2 and 8 electrons respectively. If these are completely filled, the total number of electrons in an atom is 2+8=10.
