Question
What is a primary reason for beryllium's anomalous behavior compared to other Group II metals?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Page 4 explains that beryllium is an exception because 'Its electrons are not well shielded from its nucleus.' This leads to a small ionic radius and high polarizing power.
Hint
Think about the electronic structure and size of beryllium's ion.
