The relative locations of the transition metals in the periodic table and their chemical and physical properties can best be understood by considering their electronic structures and the way in which those structures vary as atomic numbers increase. Atomic orbitals of the hydrogen atom As noted earlie...
A study was made of the electrical conductivity, thermo-emf, Hall constant, thermal conductivity, and microhardness of aluminides of some transition metals at room temperature. In addition, the thermal expansion coefficients of the aluminides were measured, and the temperature dependence of their ...
Why is it called transition metals? These metals are called transition metals as they share many physical and chemical properties with traditional metals. Yet, they are less reactive, like noble gases. Thus, they have in-between properties lending them the name transition metals.What...

Relations between the composition, structure and some physical properties of transition metal chalcogenides (sulphides, selenides and tellurides) are discussed in a qualitative way. A simple band model is given which explains the behaviour of lanthanide mono- and dichalcogenides. The model is also ap...
