Question

Show the distribution of electrons in oxygen atom (atomic number 8) using orbital diagram

Answer 1

Oxygen atomic number is 8
electronic configuration is 1s² 2s² 2p⁴
so distribution of electrons in orbitals is :

Answer 2

Answer:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration  of oxygen with atomic number of 8 contains 8 electrons

$):8:1s^22s^22p^4$

Thus K shell with n= 1 contains 2 electrons and L shell with n= 2 contains 6 electrons.
