The thirteenth element of the regular table is aluminum. The facet of group-13 is aluminum and also its prize is Al. Aluminum develops bonds with its valence electrons. This post discusses in detail the valence electrons of aluminum.

You are watching: How many valence electrons does aluminum have


What room the valence electrons of aluminum(Al)?

The 2nd element in group-13 is aluminum(Al). The valence electron is the total variety of electrons in the last orbit. The total variety of electrons in the last shell after the electron configuration of aluminum is called the valence electrons of aluminum(Al).

The valence electron determine the properties of the element and also participate in the development of bonds. The thirteenth facet in the periodic table is aluminum(Al). The is, the atom that the aluminum facet has a complete of thirteen electrons.

Valency and also valence electron of aluminum(Al)

The electron configuration of aluminum(Al) is 1s2 2s2 2p6 3s2 3s1. The electron configuration of the aluminum reflects that it has actually three unpaired electron in the critical orbital. Therefore, the valency(valence) the aluminum(Al) is 3.

How many valence electrons does aluminum ion(Al3+) have?

After the electron configuration, the last shell of the aluminum atom has three electrons. In this case, the valence(valency) the aluminum is 3. We recognize the details about this. The facets that have 1, 2, or three electrons in the critical shell(orbit) donate the electron in the last shell during bond formation.

The elements that form bonds by donating electron are referred to as cations. That is, aluminum is a cation element. Aluminum donates the electron the the last covering to kind bonds and also turns right into aluminum ions.

Al – 3e– → Al3+

The electron configuration of aluminum ion is 1s2 2s2 2p6. The electron configuration of aluminum-ion shows that aluminum ions have actually only 2 shells and also that shell has actually eight electrons. The electron configuration shows that the aluminum atom has acquired the electron configuration of neon.

That is, in this case, the valence(valency) that the aluminum-ion is +3. Due to the fact that the last shell(orbit) of an aluminum-ion has actually eight electrons, the valence electrons of aluminum-ion space eight.

Compound development of aluminum

Aluminum participates in the formation of bonds v its valence electrons. We know that the valence electron in aluminum(Al) space three. This valence electron participates in the formation of bonds with atoms of other elements.

The electron configuration of oxygen shows that the valence electrons of oxygen are six. The aluminum(Al) atom donates its valence electrons to the oxygen atom and also the oxygen atom receive those electrons.

As a result, oxygen repurchase the electron configuration of neon, and aluminum atoms also acquire the electron configuration of neon. Aluminum oxide(Al2O3) is formed by the exchange that electrons between two atom of aluminum and also three atoms of oxygen. Aluminum oxide (Al2O3) is ionic bonding.
