In thenomenclatureofinorganic chemistry, the oxidation number of an element that may exist in more than one oxidation state is indicated by a roman numeral in parentheses after the name of the element—e.g., iron(II) chloride (FeCl2) and iron(III) chloride (FeCl3). ...
Failure to prepare compounds containing an atom with the oxidation number below IV is rationalized. The paper provides an opinion on uncertainties in oxidation state determination in three kinds of compounds: binary compounds, nitrosyl complexes, and compounds containing mutually bonded atoms of the ...

Formal Oxidation Number « on: December 07, 2009, 11:17:17 PM » hey guys, I'm just wondering how to figure out the formal oxidation number of an atom in a compound when you have the lewis structure? (apparently it's totally different than formal charge)~Julie~ Logged stewie...

The increase in catalyst concentration increased the number of reactive sites and enhanced the light absorption for photocatalysis [151]. The higher concentrations of the catalyst may result in light-scattering and screening effects due to high opacity caused by an excess catalyst which compromised ...
The purpose of this study is to determine pre-service chemistry teachers' knowledge of the oxidation number and coordination number in coordination compounds. Data were collected from 31 pre-service chemistry teachers through a 4-question scale, and the second question of the scale consisted of 8 ...
