The melting point of sodium metal is 97.8 °C, and the melting point of sodium chloride is 801 °C. What can you infer about the relative strength of metallic and ionic bonding from these melting points?

Hello everyone today. We have the following problem. The melting point of calcium metal is 1,115° Kelvin calcium oxide melts at 2,886 Kelvin, which is the stronger type of bond, metallic or ionic bonding. Well, in terms of strength of bond, so in terms of bond strength it's going to be directly correlated with melting point. And so the higher the melting point, the higher or the higher the bond strength, the higher the melting point. And so we have calcium metal and we have calcium oxide. Calcium metal is going to engage in metallic bonding. Calcium oxide is going to engage in ionic bonding. An ionic bonding is just a bond between a metal and a non metal. So it makes sense that the ionic bond would be stronger in this situation because of the higher melting point. And with that we've answered the question overall. I hope this helped and until next time.
