Question

Which one of the following does not increase down the group in the periodic table?

• A. Atomic radius
• B. Metallic character
• C. Valency
• D. Number of shells in an element

The correct option is C Valency

Down the group, the atomic radius and the metallic character increases. However, the electronic configuration remains the same. Thus the valency does not change.

Thus the correct answer is option 'C'.
