Aluminum has 3 electrons in its outermost energy level.
Aluminum has 3 electrons in its highest occupied energy level.
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 electron notation for aluminum is 1s^2 2s^2 2p^6 3s^2 3p^1. This indicates that aluminum has 13 electrons, with two in the first energy level, eight in the second energy level, and three in the third 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.
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.
Two electrons can be housed in the first energy level.
The first energy level can hold up to 2 electrons.
Zinc has 2 electrons on its first energy level.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
