Electron Configuration

The electron configuration of a chemical species refers to the distribution of its electrons in atomic orbitals.

To determine the electron configuration of V ⁵⁺, we first need to know the atomic number of vanadium (V), which is 23. This means that a neutral vanadium atom has 23 electrons.

Electron Configuration of V⁵⁺

Since V ⁵⁺is a cation, it has lost 5 electrons compared to a neutral vanadium atom. Therefore, the electron configuration of V ⁵⁺is:

s²2s ²2p ⁶3s ²3p ⁶3d ⁰

Orbital Diagram

An orbital diagram represents the distribution of electrons in the orbitals of an atom or ion. It shows the number and arrangement of electrons in each energy level and subshell.

Orbital Diagram of V⁵⁺

Vanadium (V) has an atomic number of 23, meaning it has 23 electrons in its neutral state. V ⁵⁺is a vanadium ion that has lost five electrons, leaving it with 18 electrons.

The orbital diagram of V ⁵⁺is as follows:

• 1s ²
• 2s ²
• 2p ⁶
• 3s ²
• 3p ⁶
• 3d ⁰

The Aufbau principle states that electrons fill the lowest energy orbitals first. In the case of V ⁵⁺, the 3d orbitals are empty because the 4s and 4p orbitals are higher in energy. The five electrons that were lost came from the 4s and 4p orbitals.
