So I'm assuming you already know how to write your electron configurations. An atom is considered paramagnetic if even one orbital has a net spin. In other words, an atom could have 10 paired diamagnetic electrons, but as long as it also has one unpaired paramagnetic electron, it is still considered a paramagnetic atom.

In chemistry , molecular orbital theory MO theory or MOT is a method for describing the electronic structure of molecules using quantum mechanics. It was proposed early in the 20th century. In molecular orbital theory, electrons in a molecule are not assigned to individual chemical bonds between atoms , but are treated as moving under the influence of the atomic nuclei in the whole molecule.

This handy chart compiles the electron configurations of the elements up through number To arrive at the electron configurations of atoms, you must know the order in which the different sublevels are filled. Electrons enter available sublevels in order of their increasing energy. A sublevel is filled or half-filled before the next sublevel is entered. The common shorthand notation is to refer to the noble gas core , rather than write out the entire configuration.

For example, the configuration of magnesium could be written [Ne]3s 2 , rather than writing out 1s 2 2s 2 2p 6 3s 2. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert.

Updated February 02, Key Takeaways: Electron Configurations An atom's electron configuration describes the way its electrons fill sublevels when the atom is in its ground state.

Atoms seek the most stable electron configuration, so sublevels are half-filled or fully-filled whenever possible. Rather than writing out the whole electron configuration, scientists use a shorthand notation that starts with the symbol for the noble gas before the element on the periodic table.

Aufbau means "building up" in German, and the Aufbau principle states that electrons fill electron shells around atoms according to the energy level. This means that electron shells and subshells around atoms are filled from the inside out, except in some cases where an outer shell has a low energy level and partly fills up before an inner shell is full. Exceptions to the Aufbau principle are based on the fact that a few atoms are more stable when their electrons fill or half-fill an electron shell or subshell. According to the Aufbau principle, these electrons should always fill shells and subshells according to increasing energy levels. Elements such as copper and chromium are exceptions because their electrons fill and half-fill two subshells, with some electrons in the higher energy level shells. The electrons around an atomic nucleus have discrete energy levels called shells.

Molecular orbital theory

The electron configuration of an element is the arrangement of its electrons in its atomic orbitals. By knowing the electron configuration of an element, we can predict and explain a great deal of its chemistry. First we determine the number of electrons in the atom; then we add electrons one at a time to the lowest-energy orbital available without violating the Pauli principle. Here is a schematic orbital diagram for a hydrogen atom in its ground state:. From the orbital diagram, we can write the electron configuration in an abbreviated form in which the occupied orbitals are identified by their principal quantum number n and their value of l s , p , d , or f , with the number of electrons in the subshell indicated by a superscript. We place one electron in the orbital that is lowest in energy, the 1 s orbital.

The half-filled and fully-filled orbitals are more symmetrical than any other configuration and symmetry leads to greater stability. Both are 8 Balance the following equation using oxidation number method. In short, the so-called Fermi correlation which is a consequence of the Pauli principle and applies only to electrons of the like spin keeps such. Why are half- Filled and completely filled orbitals More stable. Generally, atoms want to stay in their lowest form of energy. So, the electronic configuration that we write for an atom corresponds to its lowest state of energy.


The exactly half-filled and fully filled orbitals have greater stability than other configurations. The reason for their stability are symmetry and exchange energy.


After np orbitals are filled, the next orbital filled will be :-

When an atom or ion receives electrons into its orbitals, the orbitals and shells fill up in a particular manner. You may consider an atom as being "built up" from a naked nucleus by gradually adding to it one electron after another, until all the electrons it will hold have been added. Much as one fills up a container with liquid from the bottom up, the orbitals of an atom are filled from the lowest energy orbitals to the highest energy orbitals. Larger atoms with more subshells will seem to fill "out of order", as the other factors influencing orbital energy become important. Within a shell, there may be several orbitals with the same principal quantum number.

Our carbon page has over facts that span different quantities. Each entry has a full citation identifying its source. Orbital Filling Order. This orbital forcing affected carbon transfers by modulating the hydrological processes and sea-level changes. Fill from the bottom up, with 8 electrons total. Bonding Order is 2, and it is Diamagnetic. Here is what I mean: Carbon has an electron configuration of 1s 2 2s 2 2p 2 There are four valence electrons in carbon's outermost shell that can bond: two s orbital electrons and 2 p orbital electrons.
