Q. Which one of the following has a maximum tendency to form M3 ion ?
✅ Correct Answer: (B)
Bi
Explanation: Bismuth (Bi) has the maximum tendency to form a M³⁺ ion. This is because Bismuth, which is in group 15 of the periodic table, commonly forms a +3 oxidation state (Bi³⁺) by losing three electrons. Other elements in the same group, like Nitrogen (N), Phosphorus (P), and Arsenic (As), typically form ions with a different charge or tend to gain electrons to achieve a stable configuration, but Bismuth specifically favors the +3 oxidation state due to its position in the periodic table and its electron configuration.
