Highest occupied energy level in helium

WebThe Fermi level is the highest occupied energy level at absolute zero, that is, all energy levels up to the Fermi level are occupied by electrons. Since fermions cannot exist in identical energy states ( see the exclusion principle ), at absolute zero, electrons pack into the lowest available energy states and build up a " Fermi sea " of electron energy … Web20 de set. de 2024 · Helium has a full outer shell of two s electrons.

WebExplanation: Helium only has 2 electrons and therefore it has a configuration of 1s2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas. WebAnswer (1 of 4): As you already know, electrons occupy shells.
