What classification system????

Bohr's model is one of the ea.rliest model of atom in history, modified from Ruth.erford's model.
In 1913, a D.anish physi.cts, Niels Bohr refi.ned Ruth.erford model of the atom. How.ever, he disco.vers that elec.tron can only have spe.cific amo.unts of energy. These energy levels are also known as ele.ctron shells.
As for the Lewis Dot Structure, it is the m.odel of an atom that has the che.mical symbol for the ele.ment surronded by dots to rep.resent the valence ele.ctron of the ele.ment.

HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
An ionic compound is a substance that contains atoms that are bonded together through an ionic bond, where electrons are transferred from one atom to another. For the given experiment above, the material that is missing from the list is WATER or solvent. It is necessary because conduction through water will help you identify if a sample compound is ionic through its electrolytes. <span>Ionic compounds that are soluble are typically electrolytes</span>
