Question
Beryllium is an exception to the common patterns in Group 2. Which of the following is a reason for beryllium's anomalous behavior?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The document states that beryllium has a 'Small ionic radius – representing very dense centre of positive charge and high polarizing power.' A small ionic radius and high charge density lead to high polarizing power. Options A and B describe characteristics opposite to beryllium's. Option D is incorrect; its compounds are more covalent than ionic.
Hint
Think about the size and charge density of the beryllium ion compared to other Group II ions.
