Magnesium oxide crystallizes in the rock-salt structure and has some typical semiconducting properties, such as wide valence band (~6 eV), large dielectric constant (9.8), and small exciton binding energy (<0.1 eV). The hydrates are MgCl 2.6H 2 0, CaCl 2.6H 2 0, SrCl 2.6H 2 0 and BaCl 2.2H 2 0. 3:33 700+ LIKES Basicity Decreases With The Atomic Number Of The Metal. Acidity Increases With The Atomic Number Of The Metal. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
