The noble gas configuration is a shorthand electron configuration for atoms.

You are watching: Using noble gas notation write the electron configuration for the fluorine atom.

In chemistry, the noble gas configuration is a shorthand an approach of creating an atom’s electron configuration. The factor for making use of the noble gas configuration is since the complete electron configuration becomes very long for atoms v high atom numbers.

Here is a watch at how to create a noble gas configuration and a list of the electron configuration for all 118 elements.

How to compose a Noble Gas Configuration

The noble gas configuration provides the noble gas main point that occurs prior to the facet on the regular table and also then the electron construction of the atom’s valence electrons. But, you must understand just how to compose the full electron construction to find the number of valence electrons.

Here space the procedures for composing a noble gas configuration:


Applying the Aufbau principle renders writing electron configurations lot simpler.
Find the variety of electrons for the atom. For a neutral atom, this is the same as the atom number. (For one ion, the variety of electrons is no the very same as the number of protons, however otherwise the same procedures apply.)Fill in the electron shells and energy levels v the electrons.Each s shell holds up to 2 electrons.Each p shell holds up to 6 electrons.Each d covering holds approximately 10 electrons.Each f shell holds approximately 14 electrons.

Noble Gas configuration Examples

For example, write the noble gas construction of sodium.

The atomic variety of sodium is 11, therefore you understand the neutral atom has 11 proton and likewise 11 electrons.Filling in the electron shells utilizing the Aufbau principle gives a construction of 1s2 2s2 sp6 3s1. Include up the superscripts and double-check to make sure you have actually the correct number of electrons.Write the noble gas configuration. Looking at a routine table, keep in mind the noble gas before sodium is neon. The electron construction of neon is 1s2 2s2 2p6. So, the noble gas core symbol replace instead replace that part of the sodium electron configuration. The noble gas configuration for sodium is 3s1.
