title: Magnesium
context: Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. It tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals, an oxygen-free environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove. Magnesium has the lowest melting (923K (1,202°F)) and the lowest boiling point 1,363K (1,994°F) of all the alkaline earth metals.
question: How hot can magnesium get before melting?
answers: 923
