Explanation
making use of the
element
pyramide (EP):
*
During combustion Mg reacts with oxygen (O) leaving magnesium oxide
(MgO).
*
In row 3. of the EP you obeserve the neighbouring elements N, O,
F, Ne,
Na, Mg.
*
The noble metal neon (Ne) is situated in the middle between oxygen
(O) and magnesium (Mg).
The reaction between Mg and O makes their atoms similar to a Ne atom.
