Question

state the three rules proposed by bohr and bury regarding the distribution of electrons in different orbits of atoms

Answer 1

1. The maximum number of electrons present in a shell (n) is given by the formula 2n², where ‘n’ is an integer.
2. The maximum number of electrons in the outermost orbit of an atom is 8.
3. Electrons are not accommodated in a given shell, unless the inner shells are filled, i.e., shells are filled in a step-wise manner.
 

Answer 2

1.maximum number of electrons that can be accomodated in a given shell is 8.

2.electrons can not be placed in an orbit unless the inner shells are compeletely filled.

3.electrons revolves around the nucleus in a fixed orbit known as discrete orbits
