Yttrium Electron Configuration:7 (Easy Step-by-Step Guide)

An element electron configuration shows the arrangement of electrons in the atomic orbital of an atom. Let us study the electron configuration of yttrium below.

Yttrium electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d1 5s2. It is a transition metal having symbol Y and atomic number 39. Yttrium is a silver-colored soft metal which is similar to lanthanides chemically. The oxides of yttrium are added to the glass used for making heat resistant camera lenses.

In this article, we will learn about the electronic configuration of yttrium, like writing the electronic configuration and the ground state orbital diagram etc. of yttrium .

How to write Yttrium Electron Configuration

We can follow the following steps to write the electronic configuration of yttrium.

  • At first, we will write the shell number of the yttrium. It has a five electrons shell.
  • In the second step, we will write the number of electrons present in the orbital of the yttrium. We can write the orbitals in the order of 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s 5p 5d 5f and so on.
  • In step 3, we will put the subscript and represent the final electronic configuration of yttrium as per the higher capacity of orbitals.
  • Thus, the final electronic configuration of the yttrium will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d1 5s2.

Excited State of Yttrium Electron Configuration

The excited state electron configuration of yttrium is [Kr] 4d1 5s1. In the excited state, the last valence electron of an atom absorbs the energy and occupies a higher energy level state.  

Ground State Yttrium Orbital Diagram

The ground state orbital diagram of yttrium contains filled 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p and 5s orbitals. At the same time, the 4d orbital is incomplete. It tends to occupy 10 electrons, but it comprises one single electron here. The filled orbitals contain electrons in both anticlockwise and clockwise manner.
