Electronic Configuration is something which says the number of outer most shells of an element , it's valency and it's Valence electrons
ORBITAL POSITIONS
FIRST ORBIT ALWAYS CONSIST OF 2 ELECTRONS (2)
SECOND ORBIT ALWAYS CONSIST OF 1 TO 8 ELECTRONS
(2,1) ,(2,2) , (2,3) ......... (2,8)
REMEMBER
WHENEVER OUTER MOST SHELL OF AN ELEMENT IS FILLED IT CANNOT COMBINE WITH OTHER ELEMENTS
EXAMPLE :- HELIUM , ARGON THAT IS ALL THE NOBLE GASES

Explanation:
Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. ... In terms of a more refined, quantum-mechanical model, the K–Q shells are subdivided into a set of orbitals (see orbital), each of which can be occupied by no more than a pair of electrons.
