The shells are filled in a systematic purchase, with Every single shell accommodating only a little variety of electrons. Different atoms have various figures of electrons, which happen to be distributed within a attribute electronic composition of loaded and partly crammed shells.
The arrangement of an atom’s electrons establishes its chemical Qualities. The Attributes of solids are generally predictable from the Attributes in their constituent atoms and molecules, and the different shell buildings of atoms are for that reason responsible for the diversity of solids.
