Electron configuration of oxygen

Oxygen is denoted by the letter O and its atomic number is 8. The number of electrons in Oxygen is 8. It is a highly reactive non-metal

Electron configuration of Oxygen

Electron configuration is the Arrangement of electrons in different orbitals of an atom. The electronic configuration of Oxygen is given by

1s2 , 2s2, 2p4

or

2, 6

we can write the electron configuration in the orbital diagram as below

Sometimes, we can write the electron configuration in short form as

[He] 2s2 2p4

Where [He] stands for electron configuration of Helium i.e 1s2
