Question
Why do metals in the lower half of Group 1 tend to form more complicated oxides (peroxides and superoxides)?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Page 9 explains, 'The formation of more complicated oxides (i.e. peroxides and superoxides) from the metals releases more energy and makes the system more energetically stable.' It also mentions these metals have big ions and low charge density.
Hint
Consider the energetic favorability for the formation of these compounds.
