These three main transition series are included in the set of 30 elements often called the d-block transition metals. Because scandium, yttrium, and lanthanum actually do not form compounds analogous to those of the other transition metals and because their chemistry is quite homologous to that ...

The students had a mean score of 38%, based on correct responses for both answer and reason tiers for the questions. It was accompanied by a mean confidence of only 3.49 out of 6 (that is, 58.2 %) for the whole test. The results indicate that transition metals chemistry is a difficult...

Mechanistic understanding of large molecule conversion and the discovery of suitable heterogeneous catalysts have been lagging due to the combinatorial inventory of intermediates and the inability of humans to enumerate all structures. Here, we introduce
