How would the closed shell behave differently from its incomplete version?blue_leaf77 said:Well, if your question is whether the electrons behave differently in both cases, then yes obviously they must be different. In particular, the total orbital and spin angular momentum for a closed shell atom are zero.
An electron orbital is a region in an atom where an electron is most likely to be found. It is represented as a three-dimensional space that surrounds the nucleus of an atom.
An electron orbital is completed when it contains the maximum number of electrons allowed based on the energy levels and sublevels of the atom. For example, the first energy level can hold a maximum of two electrons, while the second energy level can hold a maximum of eight electrons.
A completed electron orbital differs from an incomplete one in terms of the number of electrons present. A completed orbital has the maximum number of electrons, while an incomplete one has fewer electrons and may have unpaired electrons.
The completion of an electron orbital is determined by the number of energy levels and sublevels in an atom, as well as the number of electrons present in the atom. The Pauli exclusion principle, which states that no two electrons can have the same set of quantum numbers, also plays a role in determining the completion of an orbital.
The completion of an electron orbital affects the properties of an atom in various ways. For example, a completed orbital leads to a more stable configuration, resulting in a lower energy state for the atom. This can also affect the reactivity and chemical properties of the atom.
