Which one of the following statements is not correct about the trends in the properties of the elements of a group on going down in a group?
- The chemical reactivity of metals increases.
- The metallic character of elements increases.
- The size of the atom increases.
- The valence electrons increase
Correct Answer: (d) The valence electrons increase
Explanation: The valence electrons remains the same of the elements of a group on going down in a group.
