In a single oxygen atom, there are eight protons, eight electrons, and eight neutrons.
The initial two electrons in the electron configuration for oxygen will be in the 1s orbital. Because the 1s orbital can only store two electrons, the next two electrons for oxygen are placed in the 2s orbital.
As a result, the oxygen electron configuration is 1s22s22p4.
Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u.

What is oxygen?
Oxygen (O2) is a diatomic, colorless, odorless, and tasteless gas with 180-degree bond angles. The O2 Lewis structure is made up of two oxygen atoms bonded in a pair. Many species rely on molecular oxygen to breathe, making it essential for survival. Oxygen (as a compressed gas) is also commonly used as an oxidizer in welding, metal cutting, and rocket engines.
O2 molecular geometry
Oxygen is a diatomic molecule with linear molecular geometry and bond angles of 180 degrees.
In the O2 molecule, both oxygen atoms have equal electronegativity and both atoms share equal ratios of bonded shared electrons, and the overall molecule turns out to be nonpolar in nature.
Oxygen Density
The density (ρ) of oxygen (O2) is 1.428 g/L at a standard temperature and pressure. The molar mass of oxygen is 32 grams per mole.
One mole of a gas at STP (0°C and 1 atm) has a volume of 22.4 L. So if we have the molar mass of the gas, just divide it by 22.4 to get the density of that gas. The molar mass of O2 gas = 32 g/mol.
Density = mass/volume
Density of oxygen= (32 g/mol) / (22.4 L/mol) = 1.428 g/L
Summary
- The answer to the question “How many electrons does oxygen have?” is oxygen atom has eight electrons.
- Oxygen is a diatomic molecule with linear molecular geometry and bond angles of 180 degrees.
- Oxygen is also commonly used as an oxidizer in welding, metal cutting, and rocket engines.
