What is the highest occupied energy level of oxygen?


Updated: 2nd October 2019

What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number. Inner-shell electrons are electrons that are not in the highest occupied energy level (sometimes referred to as “Kernel Electrons”). 25.

Consequently, what is the electronic configuration of oxygen?

[He] 2s2 2p4

What is the orbital notation for phosphorus?

When we write the configuration we'll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In this video we'll use the electron configuration chart to help us write the notation for Phosphorus. Note that the last term in the Phosphorus electron configuration will be 1s2 2s2 2p6 3s2 3p3.

How many electrons are in the p orbital of oxygen?

So for the element of OXYGEN, you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom. Looking at the picture, you can see there are two electrons in shell one and six in shell two.
