electron configuration for the elements in the periodic

: 1. The elements present in same group have same number of valence electrons. 2. The total number of electron present in the valence shell of the representative elements indicates its group number. 3. The electrons are added across a period..

The arrangement of electrons in the various shells/orbits/energy levels of an atom of the element is known as electronic configuration. Keeping the Bohr and Bury rules in mind let us write the electronic configuration of elements..
