Aluminum has 3 electrons in its highest occupied energy level.
The valence electrons in lithium are located in the second energy level. Lithium has 3 electrons with 2 in the first energy level and 1 in the second energy level, which is the valence level.
The maximum number of electrons in the first three energy levels (or shells) are as follows: First energy level: 2 electrons Second energy level: 8 electrons Third energy level: 18 electrons
The third and higher energy levels can hold more than 8 electrons. The third energy level has 18 electrons, the fourth has 32, and so on. Each successive energy level can hold more electrons than the one before it.
Energy level 1 can hold up to 2 electrons, energy level 2 can hold up to 8 electrons, and energy level 3 can hold up to 18 electrons. This is based on the formula 2n^2, where n is the principal quantum number.
Phosphorus has five electrons in the third energy level (n=3).
Nitrogen has 7 electrons in total. In its ground state, nitrogen has two electrons in the 1s orbital and five electrons in the 2p orbital. Therefore, there are 3 electrons in the higher energy level (2p orbital) of nitrogen.
Aluminum has 3 electrons in its outermost energy level.
Aluminum has 3 electrons in its highest occupied 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.
Phosphorus has 5 electrons in its highest occupied energy level.
The valence electrons in lithium are located in the second energy level. Lithium has 3 electrons with 2 in the first energy level and 1 in the second energy level, which is the valence level.
There are 3 electrons in the outer energy level of a neutral boron atom. Boron has 5 electrons in total, with 2 in the first energy level and 3 in the second energy level, which is the outermost energy level.

Boron has 3 electrons in it's outer level.
The element in period 3 with 8 electrons in its outermost energy level is chlorine (Cl).
The third energy level, or third shell, of an atom can hold up to 18 electrons. This level consists of 3 subshells: s, p, and d. The s subshell can hold a maximum of 2 electrons, the p subshell can hold up to 6 electrons, and the d subshell can hold up to 10 electrons.
