Atomic Energy Levels and Subshells
The electron configuration of an atom is determined by its atomic energy levels and subshells. Each shell, designated by a letter (K, L, M, etc.), has a specific electron holding capacity. The first shell, K, can hold a maximum of 2 electrons, the second shell, L, can hold 8 electrons, the third shell, M, can hold 18 electrons, and the fourth shell, N, can hold 32 electrons. The electron holding capacity of each shell can be calculated using the formula 2n^2, where n is the number of the shell.
Visualizing the electron configuration can be done through an orbital diagram, which shows the arrangement of electrons in each subshell. The Aufbau principle is a helpful guide to determine the electron configuration of an element. According to this principle, electrons fill the lowest energy orbital first, following the order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d. This order allows for the most stable configuration of electrons within the atom.
Understanding the atomic energy levels and subshells is crucial in determining the electron configuration and overall behavior of elements. It provides insights into how electrons are arranged and distributed within an atom, which influences its chemical and physical properties. By studying the electron configuration via the Aufbau principle, scientists can gain a deeper understanding of the fundamental building blocks of matter and how they interact with each other.

Vanadium Ion and Electron Affinity
When vanadium forms ions by gaining or losing electrons, it exhibits interesting properties. The most common ions of vanadium are V2+ and V3+. The electron configuration of the V3+ ion is [Ar] 3d2, indicating that it has two fewer electrons compared to the neutral atom. The valence electrons of the V3+ ion amount to ten, as it has three shells and the last shell contains ten electrons.
Vanadium is known for its variable oxidation states, including +2, +3, +4, and +5. These oxidation states allow vanadium to participate in a wide range of chemical reactions, contributing to its versatility. The ionisation energies of vanadium, which represent the energy required to remove an electron from the atom, are documented for each ionisation energy level.
Another important property of vanadium is its electron affinity, which measures the energy change that occurs when an electron is added to the atom. For vanadium, the electron affinity is recorded to be 50.6 kJ mol-1. This value signifies the atom’s tendency to attract and bind with additional electrons.
