Higher melting point sodium
WebNaCl is a solid at room temperature, with a very high melting point (801 °C), similar to the melting points of silver (961.78 °C) and gold (1064.18 °C), although much lower than the decomposition temperature of diamond (3550 °C). An interesting difference between diamond and sodium chloride occurs on heating.

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 …
WebThe melting point of a material is primarily related to bond strength. Materials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic … WebThis increased metallic bonding gives an even higher melting point, because more energy is required to overcome these strong electrostatic interactions. We can now see that statement (C) — the number of delocalized electrons increases from sodium to aluminum — is true. And it partially explains why the melting point increases across this ...
