Definition of inner transition metals
WebAtomic core. The atomic core refers to an atom without valence electrons. The atomic core has a positive electric charge called the core charge and is the effective nuclear charge experienced by an outer shell electron.In other words, core charge is an expression of the attractive force experienced by the valence electrons to the core of an atom which takes … WebIn chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded.
