In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
There are 3 valence electrons in an atom of aluminium.
Aluminium has three valence electrons.

There are 3 valence electrons in Al (Aluminum) as it is located in group 13 of the periodic table.
For example aluminium.
Aluminium has three valence electrons and phosphorous has five, hence the latter has more.
Aluminium has a 3 valence electrons, 3s2, 3p1
Aluminium (Al) has three valence electrons.
To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
The valence of aluminium is 3+.
Valence electrons determine the reactivity of the element.
Aluminium is positioned in Group 13 because it has three valence electrons, which determines its placement in the periodic table. Group 13 elements typically have three valence electrons and exhibit similar chemical properties, making aluminium a suitable fit in this group.
