Lewis Dot Structure For Aluminum

How to draw Lewis Dot Structure for Aluminum?

Drawing Lewis Dot Structure for Aluminum is very easy. Lewis Structure for Aluminum can be found here. All you need to know is the electron number of Aluminum to draw Lewis Structure for Aluminum. Here is the Lewis Dot Structure for Aluminum:

Lewis Structure for Al

Aluminum is a gray colored light metal with the symbol “Al”, atomic number 13, and a density of 2.70 g/cm³. To draw Lewis Structure for Al, we need to know atomic number of aluminum and valence electrons of aluminum. Because atomic number is equal to the proton number of aluminum. And proton number is equal to the number of electrons in aluminum. Atomic number of aluminum is 13. It means that aluminum has 13 protons and 13 electrons.

Now, we know how many electrons aluminum atom has. It is thirteen. We need to find the valence electrons of aluminum to draw lewis structure for Al. To find valence electrons, we need to write down the electron configuration of aluminum.

Electron configuration of aluminum is: 1s2 2s2 2p6 3s2 3p1 .

Valence electrons are present at the last shell of electron configuration. Therefore, Aluminum has 3 valence electrons. Now we can draw the lewis structure for Al:

Aluminum Lewis Dot Structure

Aluminum has 13 electrons and 3 valence electrons. Valence electrons can be found at the last shell of electron configuration. Electron configuration for 13 electrons is can be written as 2 electrons for first shell of Aluminum, 8 electrons for second shell of Aluminum and 3 electrons for third shell of aluminum. So electron configuration for Al can be shown as 1s2 2s2 2p6 3s2 3p1 .

We know that aluminum has 3 valence electrons. All we need to do to draw aluminum lewis dot structure to show these 3 valence electrons of aluminum as dots. Here is aluminum lewis dot structure:

In addition to being the third most common element in the earth’s crust, aluminum is the most used metal after iron. It is the third most common component of the earth’s crust (28%, but only 8% by mass), after oxygen (47%) and silicon (47%). Although aluminum is a chemically active material, the hard and strong oxide layer formed on its surface in the air environment prevents further oxidation of aluminum, making it a highly resistant material against corrosion.

What is Aluminum?

Aluminum, which resembles silver in terms of both its color and its ability to reflect light; It is soft, non-magnetic and ductile. 27Al is the only stable isotope, making the isotope aluminum the twelfth most common element in the universe.

Aluminum and its alloys are the most preferred industrial material after steel. It is the most common and most used non-ferrous element in the earth’s crust. The most used ore for primary aluminum production is bauxite ore. Although bauxite ore is abundant in nature, it is more expensive than aluminum production from scrap. Because, in primary production, alumina is first produced from bauxite ore by a process called Bayer, and then aluminum is produced from alumina by electrolysis of molten salt.

The reason why aluminum is used in many sectors is that it has superior properties compared to other metals. The first of these features is that it is lightweight. It has a density of 2, g/cm3 and an atomic weight of 26.97 g/mol. Due to its high strength, its specific strength is also high. Its thermal and electrical conductivity is at a serious value of 61% compared to copper, according to IACS standards. The resistance of aluminum against corrosion is very high. Thanks to the alumina layer it forms on its surface, it is preferred in highly corrosive environments. Since it has a face-centered cubic crystal structure, it is easy to form. Lewis Structure for Aluminum can be found in ChemHelps. Lewis Dot Structure for Aluminum can be drawn easily.

Other properties of pure aluminum are as follows;

Atomic number: 13
Melting point: 660°C
Modulus of elasticity: 69×103 MPa
Crystal structure: face-centered cubic
