Higher melting point sodium
WebThese ions will be arranged in an ionic lattice structure. There is a strong attractive force between these oppositely charged ions, which require a lot of energy to break lots of these bonds to melt the lattice structure. This is why sodium oxide has a high melting point. Answered by • Chemistry tutor. WebBoth sodium and magnesium have metallic bonding between atoms. Outer electrons become delocalised and float freely between the positive ions. The positive ions attract the negatively charged electrons so the bond is very strong.Magnesium has a higher melting point because magnesium ions are Mg 2+ and sodium is Na +.Magnesium ions have a …
