Question

The maximum number of electrons in any shell is given by the formula ________.

Answer 1

Bohr-Bury Scheme-

• The distribution of electrons in the energy levels is given with the help of the Bohr Bury scheme, which is mentioned below.
• The energy levels or energy shells are filled in order of increasing energies.
• The maximum number of electrons in any shell is given as 2n², where n is the number of shell.
• First the inner shells are completely filled then only the filling of new shells starts.

Hence, The maximum number of electrons in any shell is given by the formula 2n².
