Question
The true statement among the following is:
- The reactive nature of Halogens increases from top to bottom of the table.
- The reactive nature for Halogens decreases from top to bottom of the table.
- Halogens are incapable of reacting with metals.
- Fluorine is the most abundant element on the earth's crust.
Hint:
Fluorine is the most reactive halogen.
The correct answer is: The reactive nature for Halogens decreases from top to bottom of the table.
- Reactivity of halogens decreases down the group.
- Fluorine is the most reactive halogen. It also means that chlorine is less reactive than fluorine, bromine is less reactive than chlorine and so on.
- As we go down the group number shells keep on adding, distance from protons increases and the electrons do not much participate in reactions.
