Answer:
Number of delocalized electrons
Explanation:
Magnesium has more delocalized electrons compared to sodium and this accounts for the higher melting point.
- When magnesium atoms comes together to form a metallic bonds, they have more network of delocalized electrons.
- There is more pull for the localized electrons due to the nuclear charge on the nucleus.
- This strong intermolecular metallic bond increases the melting point of magnesium.
The correct option would be that oxygen, nitrogen, and carbon dioxide cannot react with one another.
<h3>Why air components cannot react</h3>
The components of atmospheric air, nitrogen, oxygen, carbon dioxide, etc., cannot react with one another because there is not enough energy in the atmosphere to set the reaction rolling.
For a reaction to take place, there must be enough energy to break the bonds in each air component. This is why the air components will not spontaneously react with one another, except during special events such as lightning and thunder.

The density of a person stays the same no matter where they are in the universe
The answer is (2) increases. The definition of excited state is that the electrons have higher energy than ground state. For comprehension, the excited state is ready for reaction so it has higher energy.
