Highest occupied energy level of helium
Web8 de jan. de 2024 · Noble Gases have a very stable electron configuration, therefore, they have the highest amount of ionization energy within their periods. It decreases down a family because electrons farther from the nucleus are easier to remove. Largest to Smallest: Helium (highest ionization level in the periodic table) Web14 de ago. de 2024 · The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium. The remaining electron must occupy the orbital of next lowest energy, the 2 s orbital (Figure 8.3. 3 or 8.3. 4 ). Thus, the electron configuration and orbital diagram of lithium are:

Web8 de mai. de 2024 · What is the highest occupied energy level for helium? Their outer energy levels are full because they each have eight valence electrons. The only … 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.
