Question

plzz Explain briefly about electronic configuration?

Answer 1

It is the distribution of electrons in an atom or in a molecule. It is the representation of arrangement of electrons in orbital shells and subshells

Answer 2

Electronic Contrifugation :

we have seen that 2 8 18 32 electrons can accommodated in the shells like K, L, M, N respectively. this is the maximum capicity of that shells . The electrons in an atom are distributed in the shells according to the maximum capacity. the shell wise distribution of of the electron in an atom of an element is called the electronic contrifugation.

• Each electron has a definite energy as per the cell in which it is present
• The electronic configuration of an element is such that the energy of all the electrons together is the maximum possible.

The electron contrifugation in the numerical form contains numbers seperate by commas. Here the numbers indicate the electron number in the shells with increasing order of energy for example the electronic contrifugation of sodium is 2,8,1. It means that the total 11 electrons in sodium are distributed as 2 in the shell 'K', 8 in the shell 'L' and 1 in the shell 'M'. The electronic contrifugation of an atom can also be represented by shell diagram.
