Question
Draw a sketch of Bohr’s model of an atom with three shells.
Solution
According to Bohr's atomic model with three orbitals, the order of the three orbitals will be K, L and M
The number of electrons in each orbit = 2n2
Number of electrons in K orbit = 2 × 12 = 2
Number of electrons in L orbit = 2 × 22 = 8
Number of electrons in M orbit = 2 × 32 = 18
But the maximum number of electrons in the outer orbit can be 8.
