Normally, three.
there are 3 valence electrons in the atom of aluminum
There are 3 electron shells in Aluminum. The first shell holds 2, the second shell holds 8, and the third shell holds 3. This equals 13, its Atomic Number. http://www.chem4kids.com/files/elements/013_shells.html
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
an aluminum atom will lose the 3 electrons on its outer shell 2 for an aluminum ion.
Normally, three.

Aluminum
Aluminum has 3 valence electrons.
Yes, aluminum has 3 valence electrons.
Shell casings are typically either brass, steel, or aluminum.
Aluminum has an atomic number of 13. Thus, neutral aluminum has 13 protons and 13 electrons. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p1. We can see that 3 is the outermost shell and that there are 3 electrons found there.
Yes...along with Boron
in the middle of the shell (inside)
Helium
two dots on the first shell closest to the nucleus, eight dots on the second shell and then three dots on the outer shell to total 13 two dots on the first shell closest to the nucleus, eight dots on the second shell and then three dots on the outer shell to total 13
Here is the equation - Al3+ + 3e- -> Al
