WebBohr and Bury proposed the following rules for electron distribution. Rule 1: The maximum number of electrons present in a shell is given by the formula 2n 2, where 'n' is the shell number. Rule 2: Each energy level or electron shell is further divided into sub shells. The maximum number of electrons that can be accommodated in each sub shell is 8.
