The depiction of the electron distribution of an atom in its atomic shell is called an electronic configuration. Let us explore some facts about the electronic configuration of the chlorine atom.
Chlorine atom electronic configuration can exist in both ground state and excited state. The chlorine atom belongs to the 17th group of elements known as halogens and comes under the third period. Chlorine exists in gaseous form, and after cooling, it can convert into liquid. It looks yellow, and it is malignant.
In this article, we will acknowledge some of the facts of chorine electronic configuration, like its unabbreviated electronic configuration, notation, ground state and excited state electronic configurations.
How to write the chlorine electron configuration
The electronic configuration of the Cl atom is [Ne]3S2 3P5. The atomic number of the chlorine atom is 17; the chlorine atom has three shells. The first shell has 2 electrons, the second has eight, and the third has seven.
Chlorine electron configuration diagram
The electron configuration diagram shows electrons entering into their subshell by filling up the lowest energy orbital. According to Hund’s rule, this arrangement of electrons into their orbitals states that the lowest energy atomic orbital should fill first. Let us see the electronic configuration of chlorine.
Chlorine electron configuration notation
Cl electron configuration notation is 1S22S2 2P63S2 3P5. This notation consists of the name of the subshell, its number and the number of electrons present in the subshell in superscript.
Chlorine unabbreviated electron configuration
The unabbreviated electronic configuration of the Cl atom is 1S22S2 2P63S2 3P5.The unabbreviated electronic configuration is termed the configuration without using noble gas configuration. Unabbreviated electron configuration starts from the beginning of the 1s orbital.
Ground state chlorine electron configuration
The ground state electronic configuration of Cl atom is 1S22S2 2P63S2 3P5.Ground state electronic configuration is simply the configuration of an atom in its ground state. In the ground state also, chlorine can make bonds with other atoms since its valency is one in the ground state like HCl, NaCl etc.
Excited state of chlorine electron configuration
The excited state electronic configuration of the Cl is 1s2 2s2 2p6 3s2 3px2 3py1 3pz1 3dxy1. We know that d-subshell has 5 atomic orbitals, namely dxy, dyz, dzx, dx2-y2 and dz2. But the atomic number of chlorine is 17 so the excited state configuration of the chlorine is 1s2 2s2 2p6 3s2 3px2 3py1 3pz1 3dxy1.
Ground state chlorine orbital diagram
The ground state orbital diagram of chlorine is:
Conclusion
This chlorine is not found as an element. Its most common ore is sodium chloride. This chlorine is mainly used for the purification of water,buliding constructions, cleaning of swimming pools, production of many drugs,chlorides preparation and chlorinated solvents.
