Question

electronic configuration of electron is an atom is governed by​

Answer 1

Answer:

The electronic configuration of anions is assigned by adding electrons according to Aufbau Principle. We add electrons to fill the outermost orbital that is occupied, and then add more electrons to the next higher orbital. The neutral atom chlorine (Z=17), for instance has 17 electrons

Answer 2

Answer:

Explanation:

The Aufbau principle govern the electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. The energy of an orbital is calculated by the sum of the principal and the azimuthal quantum numbers.
