70/30 (70% tin, 30% lead) the more lead in an alloy the higher the melting point is.
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.
Look at intermolecular forces and judge from there

Molecular compounds tend to have the lowest melting points.
The lowest melting point is of course - 39 0C.
Urea, with a melting point of 133-135 0C.
Helium with a melting point of -272.905

W on the periodic table. the element with the highest melting/boiling point is tungsten.
NaCl, common table salt, has a rather high melting point. The substance with the lowest melting point is helium. Helium has no solid phase, it melts at any temperature above absolute zero.
