Are alkaline earth metals oxidizing agents


In the 8th grade, students first learn to set up reaction equations as follows:

Sodium and oxygen react to form sodium oxide (word equation)
Na + O2         N / A2O (symbol equation)

4 Na + O2         2 Well2O (reaction equation)

Later the term ┬┤redox reaction┬┤ is introduced, which stands for a combined reduction and oxidation and with the help of which such equations should be examined more closely.

The terms oxidation and reduction take on a new meaning:

 
oxidation
reduction

Reducing agent is a substance that itself is oxidized and helps to reduce another. [reducere (lat.) = to lead back]
Oxidizing agent is a substance that is itself reduced and thereby helps to oxidize another.

Let's consider a redox reaction using the example above:

Note:
This is a simplified reaction equation for didactic reasons !!

In fact, the following reaction takes place:

4 Na + O2      2 Well2 O

                                      


Note:
This is a simplified reaction equation for didactic reasons !!

In fact, the following reaction takes place:

4 Li + O2      2 li2O

                                      

So we notice ...

The reaction with oxygen results in the same stoichiometric ratio for every metal of the 1st main group (alkali metals).
In this respect, the element symbol (Na) can be exchanged for any other element symbol of the 1st main group (Li, K, Rb, Cs).
