【】What Is the Chemical Formula for Aluminum Oxide?

Al₂O₃ is the chemical formula of aluminum oxide.


Explanation:
  Hello,everyone we are going to learn and write about the formula of aluminum oxide.
Do you know the chemical formula of aluminum oxide?
If you don't know about the chemical formula of aluminum oxide,you should follow the following steps to write the chemical formula of aluminum oxide.
                    Step-1:

Aluminum oxide formula has two part.One is aluminum and the second one is oxide






 The symbol of aluminum is Al and in aluminum oxide, the charge of aluminum is (Al3+)  +3.

Besides,the symbol for oxygen is O and in aluminum oxide ,the formula of oxide is  O²-  here.                 

            Step-2:

Now place the two above formula side by side.



Al3+ O2-

              Step-3:

Now apply criss cross method to get the formula for aluminum oxide.
According to this method,the superscript of aluminum will be the superscript of oxygen.And the superscript of oxygen will be the subscript of aluminium.

                   Al₂O₃
formula for aluminum oxide

             Step-4:

 So the formula for aluminum oxide is given below:

                            Al₂O₃



In aluminum oxide formula,we get two atoms of aluminum and three atoms of oxygen.It is an ionic compound.



Explanation For Aluminum Oxide Chemical Formula:



The atomic number of Al is 13.So the electronic configuration of Al will be 1s²2s²2p⁶3s² 3p¹.

 Now aluminium will release three electrons to achive the electron configuration of iner gas in its outer mostshell.

 Al3+=1s²2s²2p⁶

 On the otherhand,the atomic number of  oxygen is 7.
O=1s²2s²2p⁴

 To achive the electronic configuration of inert gas,oxygen will take two electrons in its outermost shell.

 O2-=1s²2s²2p⁶

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electron...
