The lowest melting point is of course - 39 0C.
Helium with a melting point of -272.905
70/30 (70% tin, 30% lead) the more lead in an alloy the higher the melting point is.
Urea, with a melting point of 133-135 0C.
Covalent molecules which contain only bonds between elements of similar electronegativity. For example: Carbon and hydrogen. They must not contain polar bonds like Oxygen and hydrogen.
Helium
The melting point of magnesium is 650 degrees celcius. It has the lowest melting point among all the group II metals (alkaline earth metals), though the melting points generally decrease down the group - magnesium is an exception and has the lowest melting point among them.
W on the periodic table. the element with the highest melting/boiling point is tungsten.
For example:- melting point- boiling point- electrical resistivity- hardness- density
Generally the ionic molecules has a higher melting point.
