How to electronic configuration in easy method

Answer 1

HEYA!!!!!!!!!!!!!!!!!

HERE IS THE ANSWER TO YOUR QUESTION.....

We know that atoms consist of electrons, protons and neutrons. While the protons and neutrons are present inside the nucleus, electrons are present outside the nucleus and move in different shells. The arrangement or distribution of electrons in these shells of an atom is termed as electronic configuration. Thus, electronic configuration helps us in knowing how electrons are distributed in an atom. For example, the atomic number of sodium is 11. So, its electronic configuration will be 2, 8, 1.
