B)manganese, Mn, Group 7B(7)
C)iron, Fe, Group 8B(8)
D)cobalt, Co, Group 8B(9)
E)zinc, Zn, Group 2B(12)

Question

Quizplus · Accepted Answer

Manganese, Mn, in Group 7B(7) can achieve the largest oxidation number. This is because manganese has a higher number of valence electrons and a smaller atomic radius compared to the other transition elements listed. As the oxidation state increases, the positive charge on the ion also increases, making it harder to remove additional electrons. Therefore, the element with more valence electrons and a smaller atomic radius is more likely to achieve a higher oxidation state.
