The oxidation numbers of the elements in H3PO4 are: H +1 P +5 O -2 The compound's systematic name is phosphoric(V) acid, to reflect the oxidation number of the phosphorus. Oxidation numbers are used to track how many electrons are lost or gained in a chemical reactions. A. When considered the compound as a whole, it has the oxidation number of zero. The exceptions to this are that hydrogen has an oxidation state of −1 in hydrides of active metals (such as LiH), and an oxidation state of −1 in peroxides (such as H 2 O 2) or … The number of electrons in each of germanium's shells is 2, 8, 18, 4 and its electron configuration is [Ar] 3d 10 4s 2 4p 2. Most of the time, it doesn't matter if the term oxidation state or oxidation number is used. Some have more than one possible oxidation number. -1 B. In almost all cases, oxygen atoms have oxidation numbers of -2. This means that every C-H bond will decrease the oxidation state of carbon by 1. Assign oxidation numbers to each atom in the following compounds: HI, PBr3, GeS2, KH, As2O5, H3PO4 (the numbers should br subscripts) Mar 08 2013 06:04 PM 1 Approved Answer The oxidation number of oxygen is … Related Questions: How many structural isomers of primary amines are possible for the formula C4H11N?
