According to Bohr-Bury scheme:
1) The maximum number of electrons present in an orbit is given by the formula: 2n2
where, n = orbit number.
[1 Mark]
2) The maximum number of electrons that can be accommodated in the outermost orbit is 8.
[1 Mark]
3) Electrons are not accommodated in a given shell, unless the inner shells are filled. That is, the shells are filled in a step-wise manner.
