The electronic configuration structure of an oxygen atom is 1s² 2s²2p⁴ (Option A)
What is electronic configuration?
This is the arrangement of electrons in the atomic orbitals of an element.
How to write the electronic configuration
Oxygen has an atomic number of 8. Thus , we can write the electronic configuration using the spdf orbital notation as follows
NOTE:
- Sharp (s) = Maximum of 2 electrons
- Principal (p) = Maximum of 6 electrons
- Diffuse (d) = Maximum of 10 electrons
- Fundamental (f) = Maximum of 14 electrons
The electronic configuration of oxygen atom can be written as follow:
O (8) => 1s² 2s²2p⁴
