diamond has a 3 dimensional frame work of carbon and hence has high melting point
Sulfur is a larger molecule. It hence experiences greater Van der Waal's force.
Although they are both molecular structures, sulfur exists as S8 while phosphorus exists as P4. Sulfur has more electrons, therefore also has more Van Der Waals forces, than phosphorus. This means that it will require more heat energy to overcome these forces, causing it have a higher melting point.
CaO has a higher melting point.
Melting point (rhombic) 112.8°C, (monoclinic) 119.0°C

SO2
The melting point of sulfur is: 115,21 ºC The boiling point of sulfur is: 444,6ºC
non-metals have lower density, melting and boiling point but diamond has higher density, melting and boiling point.
Diamond is a covalent network solid, and those types of compounds have higher melting points than other types of compound.
Sulfur is a larger molecule. It hence experiences greater Van der Waal's force.
the melting point of sulfur is 115.21 degrees Celsius according to http://www.newworldencyclopedia.org/entry/Sulfur
