A periodic table will be available for the exam, but the list of rules will not be available, so this is a chance to practice using the rules to help you remember them! Placing one bonding pair of electrons between the O atom and each H atom gives H:O:H, with 4 electrons left over. It was first discovered in 1886 by C.A. The oxidation state of iron in magnetite is fractional because it is an average value. While silicon could be bought in 1998 for less than $10 per kg,[24] the price of germanium was almost $800 per kg. Elemental germanium starts to oxidize slowly in air at around 250C, forming GeO2 .
