Tin Electron Configuration:(Explained for Beginners)

by

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 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2, 4d10, 5p2consists 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 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2, and 4d10, 5p2 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 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2,4d10, 5p2

Tin electron configuration diagram

The electronic configuration of the Tin is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2, 4d10, 5p2 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 –
