उत्तर
- 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.
- The maximum number of electrons possible in the outermost shell is 8 and that in the penultimate shell is 18.
- It is not necessary for an orbit to be completed before another is formed. In fact, a new orbit is formed when the outermost shell attains 8 electrons.
