Question: What two first row transition metals have unexpected electron configurations A
What two first-row transition metals have unexpected electron configurations? A statement in the text says that first-row’ transition metal ions do not have 4s electrons. Why not? Why do transition metal ions often have several oxidation stares, whereas representative metals generally have only one?
