# Why the atoms attempt to obtain the stable configuration of 8 electrons Like Br has 35 electrons so it needs to get 18 electrons for the third level not 8 electrons?

An atom may hold maximum 8 electrons in its outermost shell 2 in 's' orbital and 6 in 'p' orbitals, the next incoming electron enters in next energy level because next 's' orb
