Aluminium
Al: 13
2.8.3
So three energy levels
Aluminum has 3 electrons in its outermost energy level.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
Aluminum atoms have 13 electrons, distributed across different energy levels or shells. The electron configuration of aluminum is 2-8-3, with 2 electrons in the first energy level, 8 in the second, and 3 in the third. This arrangement allows aluminum to form ionic compounds and exhibit properties such as conductivity and malleability.
Phosphorus (P) because of the 5 valence electrons total, 3 of them are in the 3p sublevel, and according to Hund's rule, they "single-fill" each orbital first.
The answer to this question is that the oxidation number for the 2nd energy level is +2. This is because the 2nd energy level is the second highest energy level in an atom, and thus has a higher oxidation number than the 1st energy level. The oxidation number for the 2nd energy level is determined by the number of electrons in the 2nd energy level.
Aluminum has 3 electrons in its outermost energy level.
Aluminum has 3 electrons in its highest occupied energy level.
n = 1: 2 electrons n = 2: 8 electrons n = 3: 3 electrons
It depends on what elements are involved. Iron has two electrons in its outer shell, Lead has four. While in a metal, the outer electrons flow freely over the surface of the solid, there is no net loss or gain of electrons, the atoms do not become ionized, and are considered to still have their original number of electrons.

yes.they have the maximum number of electrons in their outer energy level?
There are 3 electrons in the outermost level of aluminum. Aluminum is in Group 13 and has 3 valence electrons.
