Question

write down the electronic configuration of oxygen.

Answer 1

O- 1s^2 2s^2 2p^4
Is the electronic configuration of oxygen.
O-(2,6).

Answer 2

The electrons of an atom are arranged in a particular arrangement in different electronic orbitals.

And every atom has a particular arrangement of electron in these electronic orbitals which is also known as the electronic configuration.

To write down the electronic configuration of an atom ,we have to know the total number of electrons of that atom.

Total number of electrons in normal oxygen atom is = 8.

So it's electronic configuration will be,
