Question

Using the formula, find the maximum number of electrons in the following shells: K shell.

Answer 1

According to Bohr's atomic model, the maximum number of electrons a shell can occupy is given by the formula 2n² where n is the shell number.

For K shell, n = 1, using formula 2n², the maximum number of electrons that can be filled in K shell = 2 x (1)² = 2 x 1 = 2.
