Oxygen Electron Configuration: Oxygen (O) is a colorless, odorless, and highly reactive gas with an atomic number of 8. It is the life-supporting element that makes up about 20.95% of Earth’s atmosphere, making it essential for human survival, animal life, and combustion. Oxygen is also the most abundant element in the Earth’s crust, where it occurs primarily in the form of silicates, oxides, carbonates, and minerals. Thanks to its vital role in respiration, industrial processes, and chemical reactions, oxygen is one of the most important elements in science.

Oxygen Electron Configuration
The symbol of Oxygen is O, and it belongs to Group 16 (the Chalcogens) in the periodic table. As a highly reactive nonmetal and powerful oxidizing agent, oxygen readily combines with most elements to form oxides and other compounds. If you’re looking for the Oxygen electron configuration, orbital diagram, valence electrons, electron shell distribution, or other atomic properties, this guide covers everything you need to know in a simple and easy-to-understand format.
Electron Configuration For O Ion
The O⁻ ion (oxygen anion) is formed when a neutral oxygen atom gains one extra electron. Since oxygen has an atomic number of 8, a neutral oxygen atom contains 8 electrons. After gaining one electron, the O⁻ ion has 9 electrons.
Electron Configuration of O⁻
1s² 2s² 2p⁵
The O⁻ electron configuration shows that oxygen gains one electron, resulting in nine total electrons. This ion is less common than the oxide ion (O²⁻), which has the stable noble gas electron configuration 1s² 2s² 2p⁶, the same as neon.
Full Electron Configuration For Oxygen
Oxygen’s Atomic no. = 8 So the configuration is 1s22s22p4
Ground State Electron Configuration For Oxygen
The ground state electron configuration for Oxygen (O) represents how its 8 electrons are arranged in the lowest possible energy levels. Since oxygen has an atomic number of 8, it contains 8 protons and 8 electrons in a neutral atom.
The ground-state electron configuration of Oxygen is:
1s² 2s² 2p⁴
In noble gas notation, it is written as:
[He] 2s² 2p⁴
This configuration shows that the first energy level (1s) is completely filled with 2 electrons, the second energy level contains 2 electrons in the 2s orbital, and the remaining 4 electrons occupy the 2p orbitals according to the Aufbau principle, Hund’s rule, and the Pauli exclusion principle. Oxygen has 6 valence electrons, making it highly reactive and capable of forming stable chemical bonds with many elements.
See the image below for ground state electron configuration of O.
What is the Electron Configuration of O
The distribution of electrons of an atom or molecule in atomic or molecular orbitals is called the electron configuration. For example, the electron configuration of the oxygen is [He] 2s2 2p4. Oxygen is very important element of periodic table and many other gases and liquid can be created with the combination of O.
How many Valence Electrons are in Oxygen
There is Six valence electron in the Oxygen. You can see the above Orbital Dot Diagram. The symbol of Oxygen is O and the atomic Mass of Oxygen is 16.
