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 ...
Coordination chemistry & homogeneous catalysis Among the most significant developments in the field of catalysis in recent years have been the discovery and elucidation of a variety of new, and often unusual, catalytic reactions of transition metal ions and coordination compounds. Ex... HALPERN,JACK ...
It is argued that the terms valence, covalence, hypervalence, oxidation state, and coordination number are often confused and misused in the literature. It is recommended that use of the term valence, and its associated terminology, should be restricted to simple molecular main group substances and...

Knowledge of the oxidation state of metal centres in compounds and materials helps in the understanding of their chemical bonding and properties. Chemists have developed theories to predict oxidation states based on electron-counting rules, but these can
This is because of the surface stress of nanoparticles that are induced by the surface atoms with unsaturated coordination. Thus, it is indicated that the low-coordinated oxygen atoms on the surface of a nanoscaled iron-based OC can significantly enhance CO formation. Sign in to download hi-res...
Urea, present in both industrial and mammal urine (2–2.5 wt%), poses a significant environmental threat as more than 80 % of effluents directly enter nature annually [1]. Natural decomposition of urea produces compounds containing ammonia and nitrate, which can damage the environment and human ...
An electrochemical sensory platform is presented for determination of sumatriptan (SUM) in aqueous solutions and human blood serum. A pencil graphite electrode (PGE) was electrochemically delaminated by cyclic voltammetry technique, and then further modi
