Iron can be transformed to steel (an alloy), which is more resistant to rust. Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. It has the same structure as NaCl but because it is made of Mg 2+ and O 2 – ions, rather than the singly charged Na + and Cl – ions, there is a … ions.
