2018/4/6· 2 Ca + O 2 → 2 CaO (calcium oxide) 4 Al + 3 O 2 → 2 Al 2 O 3 (aluminium oxide). The transition metals (such as iron, copper, zinc, and nickel) are slower to oxidize because they form a passive layer of oxide that protects the interior. Others, like palladium, platinum and gold do not react with the atmosphere at all.

Beryllium was discovered as an oxide in both beryl and emeralds in 1798. Beryllium is found in bertrandite, beryl, chrysoberyl, phenacite, and many other minerals. The metal, steel-gray in color, is one of the lightest metals and has a high melting point.

Why metal (alkali) fluorides have high melting and …

Due to small size of fluorine atom, it has high charge to radius ratio compared to iodine. Hence, lattice energy of metal fluoride is higher then that of metal iodide. Due to high lattice energy, more energy is required to break fluoride lattice compared to iodide lattice. Hence, melting point of fluoride is higher.

Calcium - Wikipedia

The melting point of a material is primarily related to bond strength. Materials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic weight, and electron structure--can also influence the melting point. Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals.
