Simple electronic configuration question.

In summary, electronic configuration is the arrangement of electrons in an atom or molecule, indicating the number of electrons in each energy level and orbital. It is written by listing the number of electrons in each level and orbital. The purpose of electronic configuration is to organize and understand the electron distribution, and it is determined by the number of electrons in the outermost energy level. The noble gas configuration, where the outermost level is full, is considered a stable configuration and elements often react to achieve this state.

Why is something like Fluorine written as [tex]1s^{2}\;\;2s^{2}\;\;2p_{x}^{2}\;\;2p_{y}^{2}\;\;2p_{z}^{1}[/tex] and not [tex]1s^{2}\;\;2s^{2}\;\;2p_{x}^{2}\;\;2p_{y}^{1}\;\;2p_{z}^{2}[/tex]?

[tex]2p_{y}^{1}[/tex] and [tex]2p_{z}^{1}[/tex] should be of the same energy, right?

Or is it only a matter of convenience/convention which one we write?

Where do you see fluorine written this way. I always thought the various suborbitals (x,y,z) of the p orbitals were degenerate so any way you write it would be OK but why would you choose one over the others? I've never seen it written this way.
 

What is electronic configuration?

Electronic configuration is the arrangement of electrons within an atom or molecule. It shows the number of electrons in each energy level and the specific orbitals that the electrons occupy.

How do you write electronic configuration?

Electronic configuration is written by listing the number of electrons in each energy level, followed by the letter symbol for the energy level and the number of electrons in each orbital. For example, the electronic configuration for carbon is 1s2 2s2 2p2, indicating 2 electrons in the 1s energy level, 2 electrons in the 2s energy level, and 2 electrons in the 2p energy level.

What is the purpose of electronic configuration?

The purpose of electronic configuration is to provide a way to organize and understand the distribution of electrons in an atom or molecule. It helps to explain the properties and behavior of elements and compounds.

How is electronic configuration determined?

Electronic configuration is determined by the number of electrons in an atom's outermost energy level. This can be found by using the atomic number of the element and following the Aufbau principle, Hund's rule, and the Pauli exclusion principle.

What is the significance of the noble gas configuration?

Noble gas configuration refers to having a full outermost energy level, similar to the noble gases on the periodic table. This is a stable electronic configuration and elements often react to achieve this configuration, as it is energetically favorable.
