Answer 2

Answer:

The position of Mg is 12th and its oxide is $MgO$.

Explanation:

Magnesium belongs to the 2A group of the periodic table which contains all the alkaline earth metals.

The atomic number of Magnesium is 12.

The atomic mass of Magnesium is 24 amu.

The oxidation number of Magnesium is +2. It loses maximum of 2 electrons to gain a complete octet and a noble gas configuration.

It reacts with oxygen to form Magnesium oxide.

$2Mg + O_{2}$ → $2MgO$

Two moles of Magnesium atoms react with one mole of Oxygen molecules to produce two moles of Magnesium oxide.
