Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.

The oxidation number of aluminum is typically +3, as it tends to lose its 3 valence electrons to achieve a stable electron configuration.
Aluminum has 3 valence electrons
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
To find the total number of valence electrons in ALAS (which consists of aluminum (Al), sulfur (S), and four oxygen atoms), we first determine the valence electrons for each element. Aluminum has 3 valence electrons, sulfur has 6, and each oxygen atom has 6 valence electrons, totaling 24 for four oxygens. Therefore, the total number of valence electrons in ALAS is 3 (Al) + 6 (S) + 24 (O) = 33 valence electrons.
Boron has 3 valence electrons.Boron has 3 valence electrons.
The element is aluminum (atomic number 13). In its electron-dot structure, aluminum will show three valence electrons arranged around the element's chemical symbol.

To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
