♥️♥️◽◽♥️♥️

The electrons first occupy the shell with the lowest energy i.e., closest to the nucleus. The first or the innermost energy shell (K or n = 1) can take only two electrons. The second shell (L or n = 2) can contain upto 8 electrons. From third shell (M or n = 3) onwards, the shells become bigger.
