-Which is the most common ion formed by element D on the above periodic table? A)B⁺ B)B²⁺ C)B³⁺ D)B⁷⁺

Question

Quizplus · Accepted Answer

Element D, with the configuration B³⁺, indicates it has 3 valence electrons (in the P block, with 13 electrons in the outer shell). Elements tend to achieve a stable electron configuration by either losing or gaining electrons to fill or empty their outer shell. Losing 3 electrons to achieve a noble gas configuration is more feasible than gaining 5, so the most common ion would have a +3 charge, corresponding to option C.
