Calcium''s melting point is variously quoted as 839°C or 842°C. All of the transition metals following it in the Periodic Table have higher melting points(apart from zinc, which doesn''t count as a transition metal). This is because one of the factors which control melting point is the nuer of electrons which are involved in the metallic bond.

Carbon, found in coal deposits, is the chemical with the highest melting point. The chemical element with the highest melting point is carbon, at 4300–4700 K(4027–4427 °C, 7280–8000 °F). The second highest melting point of the chemical elements is tungsten, at 3695 K (3422 °C, 6192 °F), which is why it is used as a filament for light bulbs. Sometimes tungsten is called the element with the highest melting point because carbon does not actually melt …

Alkali and Alkaline Earth Metals - TechnologyUK

Metallic bonds in the alkaline earth metals are thus stronger than for the alkali metals, resulting in higher melting points, but they are still quite reactive because the two outer electrons are easily lost. As a result, they are not found in nature in their elemental state. All but one of the alkaline earth metals react with the halogens
