Question Detail
Question
The general trend down the groups of the periodic table is?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Down a group, atomic radius increases, and for metals, reactivity generally increases (for nonmetals in groups like halogens, reactivity decreases). The most common general trend taught is that metallic character and reactivity of metals increase down a group.
Hint
Consider the reactivity of alkali metals down the group.
