As atomic number increases, electrons progressively fill these shells and subshells more or less according to the Madelung rule or energy ordering rule, as shown in the diagram. Note that the textbook and my hand-drawn answer start at the 2sigma MO, not the 1sigma MO—that's just shorthand for ease of drawing, since MOs below 2sigma do not vary in energy level or number of electrons (in. This sounds like something that would be tough, but orbital filling diagrams are really just pictures that show you the same thing as electron configurations. It also explains the bonding in a number of other molecules, such as violations of the octet rule and more molecules with more complicated bonding (beyond the scope of this text) that are difficult to describe with Lewis structures.
