What then do we call #1?chemisttree said:#2 is the winner!
Why then is the filling of subshell much more important for chemical properties?Borek said:I don't think it has a special name. Yes, it is a correct number of electrons on each shell, but it is filling of subshells that is much more important for chemical properties. That's why we prefer #2, as it tells as much more.
And yes, thanks to Aufbau principle they are to some degree equivalent.
Because it tells you which orbitals the valence electrons are in, and they are the most important electrons to understand things like the spectrum of atoms and chemical reactivity.Chijioke said:Why then is the filling of subshell much more important for chemical properties?

Electronic configuration is the arrangement of electrons in an atom, molecule, or other physical structure. It describes the distribution of electrons in different energy levels, sublevels, and orbitals.
Understanding electronic configuration is important because it helps us understand the chemical and physical properties of elements and compounds. It also allows us to predict how atoms will bond and interact with each other.
Electronic configuration is determined by the number of electrons in an atom and the rules of quantum mechanics. The Aufbau principle, Pauli exclusion principle, and Hund's rule are used to determine the specific arrangement of electrons in an atom.
The valence electrons are the outermost electrons in an atom and are responsible for an element's chemical properties. They determine how an atom will bond with other atoms to form compounds.
The electronic configuration of an element changes as the number of protons and electrons increase. This results in a change in the number of energy levels and sublevels, as well as the arrangement of electrons in orbitals. The pattern of electronic configuration can be seen in the periodic table of elements.
