2 valence electrons are in an aluminum atom in the ground state.
Aluminum atoms have three valence electrons in the ground state, as do all elements in Group 13 (Group 3A).
alliminium has a valance total of Al3+
Aluminium has 3 valence electrons.
The total number of valence electrons in Boron's ground state is 2
there are 3 valence electrons in the atom of aluminum
Aluminium and gallium are members of the 13th group of the Mendeleev periodic table of elements.
13 protons would indicate the element is aluminum, Al. It has the electron configuration of1s2 2s2 2p6 3s2 3p1. In the 3rd energy level, there are 3 electrons, thus it has a total of 3 valence electrons.
The +3 on aluminum refers to its oxidation number. The oxidation number of an atom is the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom. In this case, aluminum needs three valence electrons to form an octet (to have a total of eight valence electrons). If aluminum were to react with phosphate, PO4-3, the two would share their valence electrons and balance out, forming AlPO4.

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.

Alkaline earth metals are group 2 elements and have 2 valence electrons.
A fluorine atom in the ground state has 7 valence electrons.
