Scandium is a silvery-white metal with a melting point of 1541 °C and a density of 3.0g/cm3. It is a soft metal that slowly changes colour to yellowish or pinkish when exposed to air due to the formation of scandium oxide (Sc2O3) on the surface. It has no known biological role but is a suspected carcinogen.

melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. When all the solid has melted, additional heat will raise ...
Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
