Question

summarize the rules for writing of distribution of electrons in various shells for the first eighteen elements. ​

Answer 1

Answer:

Summarise the rules for writing of distribution of electrons in various shells for the first eighteen elements.

(ii) The maximum number of electrons that can be accommodated in the outermost orbit is 8.

(iii) Electrons are not accommodated in a given shell unless the inner shells are filled.

Answer 2

Answer:

The distribution of elements in different orbits is governed by a scheme called Bohr-Bury scheme. There are following rules:

(i) The maximum number of electrons present in any shell is given by the formula In1.

Where n = no. of orbit.

(ii) The maximum number of electrons that can be accommodated in the outermost shell is 8.

(iii) Electrons in an atom do not occupy a new shell unless all the inner shells are completely filled.
