Question

The charge/radius ratio of $Be$ and $Al$ is same because:

• A. both belongs to the same group
• B. both belongs to same period
• C. digonal relationship
• D. none of these

Answer 1

Answer: (C)

digonal relationship

Option $\left(C\right)$ is correct.

The charge/radius ratio of $Be$ and $Al$ is same because of diagonal relationship and hence these two elements possess similar deforming power.
