Question

Explain the rule according to which electrons are filled in various energy levels. ​

Answer 1

Answer:

(i) The maximum capacity of a shell to accommodate electrons is given by the general formula 2n², where n is the serial number of a shell.

(ii) The maximum number of electrons possible in the outermost shell is 8, and penultimate shell is 18.
