What is the Ground state electron configuration for oxygen?

Answer 1

O: 1s22s22p4

Answer 2

The ground state electron configuration for oxygen is 1s^2 2s^2 2p^4. Oxygen has 8 electrons, and the configuration represents the arrangement of these electrons in the energy levels and sublevels of an oxygen atom in its most stable state.

Answer 3

O2- ion has same configuration as oxygen atom but just has two electrons removed from the outermost shell.

Elec. config. of O- 1s22s22p4.

Elec. config. of O2- - 1s22s22p2.

Answer 4

1s^2 2s^2 2p^4

Answer 5

1s^2 2s^2 2p^4
