Question

What is the relation between electronic configuration and stability?

Answer 1

Explanation:

Electronic configuration is the filling arrangement of the electrons among the shells of atom at increasing energy level. One shell can hold the number of electrons according to 2n2 format. where n=number shell.

If outer most shell of an atom contains 8 number of valance electrons, then its electronic configuration called stable electronic configuration. If outer most shell of an atom contains less than or more than 8 valance shell, then its electronic configuration called unstable electronic configuration.

Here for k, n=1, So k shell can hold maximum 2(1)power2= 2 electrons

Answer 2

Elements that have the same number of valence electrons often have similar chemical properties. Electron configurations can also predict stability. An atom is at its most stable (and therefore unreactive) when all its orbitals are full. The most stable configurations are the ones that have full energy levels.
