Why does H2O have a lower melting point than MgO

Chemistry
1 answer:
Vesnalui [34]3 years ago
4 0

Answer:

Magnesium Oxide (MgO) has a higher melting point than Sodium Chloride (NaCl) which is around 2,800 degrees Celcius. This is because its Mg2+ and O2- ions have a greater number of charges, and so form stronger ionic bonds, than the Na+ and Cl– ions in Sodium Chloride.
