How many electrons in the 1st energy level

WebJan 30, 2024 · The innermost shell has a maximum of two electrons, but the next two electron shells can each have a maximum of eight electrons. This is known as the octet rule which states that, with the exception of the innermost shell, atoms are more stable energetically when they have eight electrons in their valence shell, the outermost electron … WebThe number of electrons in each sublevel Electrons fill in energy order (Aufbau Principle) not energy level order. NOTE-Some Principal Energy Levels start to fill before previous ones finish. ex 4s fills before 3d, because 4s has less energy than 3d. It must fill first.
