1. The oxidation number of an element in its free state is zero.Example: The oxidation number of Zn, Al, H2, O2, and Cl2 is zero2. The oxidation number of a monatomic ion is the same as the charge on the ion.Example: The oxidation number of Na+ is +1, Mg2+ is +2, Al3+ ...
So, the charges denote the number of bond pairs it can make with others. The oxidation state of a molecule is the sum of the oxidation states of the atoms in the molecule.Answer and Explanation: To find the oxidation state of Chromium in [Cr(NH3)4Cl2]Cl. The oxidation state of a ...
Therefore, the influence of a longer time at 1200 oC or higher temperatures on the oxidation behavior is urgently deserved to be investigated. In the present work, the oxidation behavior of Cr-coated Zr cladding prepared via physical vapor deposition (PVD) was systematically investigated at 1200...
