Classify each of these elements as representative, transition, or inner transition; state whether each is a metal or a nonmetal; and give its normal phase: Main Difference – Transition Metals vs Inner Transition Metals. (a) Potassium (b) Oxygen (c) Magnesium (d) Phosphorus I figured these out by … In the United States, the labels traditionally were numerals with capital letters. So the only suited answer is D, halogen, that's a gasoline below wide-spread PT circumstances. For transition metals, the valence electrons are in the d sub-shell, and in a d-d transition, the electron is excited from one d level to another. The nomenclature of the complexes is patterned after a system suggested by Alfred Werner, a Swiss chemist and Nobel laureate, whose outstanding work more than 100 years ago laid the foundation for a clearer understanding of these compounds. So the only suited answer is D, halogen, that's a gasoline below wide-spread PT circumstances. Classification of metals Since metals are those elements capable of losing electrons, they can be divided into typical, less typical, transition, and inner transition metals. (a) Dimitri Mendeleev is widely credited with creating (b) the first periodic table of the elements. Preparation, properties of potassium dichromate, oxidizing properties. These are almost as reactive as the alkali metals, and all actinides are toxic, and they have no commercial value. anything!!
