Tin belongs to group 14 of the periodic table of elements with the symbol ‘Sn’. Let us focus on the electronic configuration of tin in this article.

**The electronic configuration of the Tin atom 1s ^{2}, 2s^{2}, 2p^{6}, 3s^{2}, 3p^{6}, 4s^{2}, 3d^{10}, 4p^{6}, 5s^{2}, 4d^{10}, 5p^{2}consists of 50 electrons**

**and is**

**known as post-transition metal present in the 14th group of P- blocks in the periodic table. Tin is also used in alloy formation as it has two allotropes and a diamond cubic structure.**

We will discuss some facts about the electronic configuration of Tin such as the writing of electronic configuration with the electronic configuration notation and orbital diagram.

**How to write Tin electron configuration**

**The electronic configuration of the Tin is 1s ^{2}, 2s^{2}, 2p^{6}, 3s^{2}, 3p^{6}, 4s^{2}, 3d^{10}, 4p^{6}, 5s^{2}, and **4d

^{10}, 5p

^{2}and is written using the following steps, where-

**S orbital has 2 electrons.****P orbital has 6 electrons.****D orbital has 10 electrons.****F orbital has 14 lelctrons.****Different orbitals can accommodate a certain number of electrons that are filled as per Aufbau’s principle, Pauli’s exclusion principle, and Hund’s rule.****Thus the electronic configuration of the Tin is 1s**4d^{2}, 2s^{2}, 2p^{6}, 3s^{2}, 3p^{6}, 4s^{2}, 3d^{10}, 4p^{6}, 5s^{2},^{10}, 5p^{2}

**Tin electron configuration diagram**

**The electronic configuration of the Tin is 1s ^{2}, 2s^{2}, 2p^{6}, 3s^{2}, 3p^{6}, 4s^{2}, 3d^{10}, 4p^{6}, 5s^{2}, 4d^{10}, 5p^{2} and is expressed in the form of the diagram as given below**

**1s orbital has the maximum energy and is filled first with 2 electrons**

**Then, 2s orbital with a maximum capacity of 2 electrons.**

**Again, 2p orbital with 6 electrons.**

**Then, 3s with 2 electrons and 3p with 6 electrons.**

**Then, 4s with 2 electrons and 3d with 10 electrons with the maximum capacity.**

**Again, 4p with 6 electrons and 5s with 2 electrons**

**After this, 4d with 10 electrons and 5p with two electrons.**

**So, the diagram will be as follows –**

**Conclusion**

Tin is a metal with 50 electrons in the atom and cannot easily oxidize in water and air. Due to its high stability and non-toxicity Tin can be used in making cans in food industries and Tin plated steel is widely used nowadays as Tin is resistant to corrosion.
