Write the postulates of bohr bury scheme of filling the electron and different orbits
Answers
Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable.
1st energy level is K shell2nd energy level is L shell
3rd energy level is M shell4th energy level is N shell and so on.
There are some examples where this rule fails... there the Afbau Principle comes:
Sometimes the electronic configuration is also described by box notation form i.e., putting an arrow for single electron in a box or a pair of arrows for two electrons in a box. The direction of the arrows gives the orientation of its spin.Further the box is labelled on top by writing the symbol of the orbital.
Answer:
1.... The maximum number of electrons that can be accomodated in an orbit or shell is equal to 2n²,where n is the number of shell.. 2n² rule......
