  • TRANSITION ELEMENTS

    TRANSITION ELEMENTS What are transition elements? Give the names of the metals of the first transition series. The elements in which the differentiating electron enters into d – orbital are called d – block elements. The d – block-elements are arranged in 4 series and 10 groups. These elements are present between electropositive s – […]
