What is the highest oxidation state for each of the elements from Sc to Zn?

Video transcript

All right. Hi everyone. So this question says to consider the oxidation states of the elements from scandium to zinc, which has the highest oxidation state option. A says manganese, option B says zinc option C says copper and option D says iron. Now recall that all of the elements listed here happened to be D block elements or transition metals. So in the periodic table, Gandi um is the first element in the D block followed by titanium vanadium, chromium, manganese iron, Cobalt, nickel copper and lastly zinc. Now scandium is in group three B of the periodic table titanium as in four B vanadium and five B et cetera until you get to iron iron, Cobalt and nickel, all of which are part of group eight B after which copper is part of one B and zinc is part of two B group to be. Now recall the elements in groups three B to seven B have an oxidation state or rather a highest oxidation state that is equal to their group number. On the other hand, elements in group eight B have a highest oxidation state that is less than their group number. So let's consider the oxidation states of all of the metals or all of the elements listed in the answer choices. The first of which being manganese now because manganese is in group seven B of the periodic table, its highest oxidation state is positive seven. Now for zinc, zinc is in group two B of the periodic table which means that its highest oxidation state is positive too. Copper is in group one be here. The periodic table which if you recall means that its highest oxidation state is also positive too. And lastly iron is in group eight B, which means that its highest oxidation state is going to be less than the group number eight, specifically, it is positive six. So with all that being said of the choices listed here, manganese has the highest oxidation state of positive seven. So our answer is going to be option A and the multiple choice. And with that being said, thank you so very much for watching and I hope you found this helpful.
