To approach it from another angle, you could think of adding an electron as changing the electron configuration to the next element on the periodic table. And then we're going to This is a way to specify the occupation of the orbitals, progressively filling the periodic table. To attain a neutral salt, there must be both a component of a strong acid and a component of a strong base in the salt. So electrons exists in clouds in a way around the nuclei of atoms.
