magnesium + Oxygen = Magnesium oxide
(reactant) (reactant) (Product)
Melting point = 651 214 2800

Question = Compare the melting point of magnesium oxygen and magnesium oxide.

Irrelevant answers will be reported

Answer 1

Answer:

a magnesium oxide is ionic compound and as we all know that ionic compounds have very high melting poin , where magnesium and oxygen are the elements so the have low melting point as compared to magnesium oxide

Answer 2

Answer:

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. But some are higher than others.

The greater the charge on the ions, the stronger the forces holding them together. Sodium chloride is made from Na+ ions and Cl- ions and has a melting point of 801°C. Magnesium oxide is made from ions with two charges (Mg2+ and O2-) and so has a much higher melting point of 2852°C.
