Let us delve into the advanced tools and resources that will facilitate a deeper comprehension of electron configuration analysis, focusing primarily on the periodic table and electron configuration charts.
The Periodic Table as a Configuration Key
The periodic table is more than just a list of elements; it is a meticulously organized chart that reflects the underlying electronic structure of atoms.
Let us delve into the precise, step-by-step method for elucidating Cobalt's electron configuration.
Applying the Aufbau Principle to Cobalt
The Aufbau principle dictates that electrons first occupy the lowest energy levels available. The nucleus, containing protons and neutrons, is surrounded by electrons arranged in specific energy levels or shells.
He has a good conceptual knowledge on different educational topics and he provides the same on this website. Elements within the same group (vertical column) exhibit similar chemical properties. Therefore, the electrons will first enter the 1s orbital. The cobalt atom exhibits Co2+ and Co3+ ions.
The cobalt atom donates two electrons in the 4s orbital and an electron in the 3d orbital to convert a cobalt ion(Co3+).
Co – 3e– → Co3+
The electron configuration of cobalt ion(Co3+) is 1s2 2s2 2p6 3s2 3p6 3d6.
The 3p subshell is now full. The next two electrons will enter the 2s orbital just like the 1s orbital. Good luck with your studies!
The information on this page is ✔ fact-checked.
In the cobaltorbital diagram, the 1s subshell holds two electrons, the 2s subshell carries another pair, the 2p subshell encompasses six electrons, the 3s subshell contains two electrons, the 3p subshell carries six electrons, the 4s subshell holds two electrons, and the 3d subshell carries seven electrons, totaling twenty-seven electrons.
To depict the cobalt orbital diagram, begin by determining the number of electrons from the periodic table.
These circular paths are called orbits (shells or energy levels). This is clearly shown in the figure of the orbital diagram of cobalt.

Cobalt ion(Co2+, Co3+) electron configuration
The ground state electron configuration of cobalt is 1s2 2s2 2p6 3s2 3p6 3d7 4s2.
The value of ‘l’ is from 0 to (n – 1). For example, the noble gas configuration of cobalt will involve using Argon (Ar).
By mastering these fundamental concepts, we equip ourselves with the tools necessary to decipher the electron configuration of cobalt and, consequently, to understand its chemical properties and behavior.
Decoding Cobalt's Electron Configuration: A Step-by-Step Guide
To comprehend the electron configuration of cobalt, a firm grasp of the underlying principles is essential.
The maximum electron holding capacity in N orbit is 2n2 = 2 × 42 = 32 electrons.
Therefore, the maximum electron holding capacity in the first shell is two, the second shell is eight and the 3rd shell can have a maximum of eighteen electrons.
The atomic number is the number of electrons in that element.
These sublevels are denoted by the same letters as the orbitals: s, p, d, and f.
The number of sublevels within a given energy level is equal to the principal quantum number (n). For cobalt (Co), with an atomic number of 27, this means we sequentially fill the orbitals.
Following the order of increasing energy, we arrive at the configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁷.
This sequence represents the ground state electron configuration of cobalt.
Hence, the electron configuration of cobalt will be 1s2 2s2 2p6 3s2 3p6 4s2 3d7.
The electron configuration of cobalt refers to the arrangement of electrons in the cobalt atom’s orbitals.
Since the 1s orbital can hold only two electrons, the next two will enter the 2s orbital.
