Which of the following is the most reactive group of non-metals?
- Alkali
- Alkali earth
- Halogen
- Noble gas
Hint:
Halogens are most reactive.
The correct answer is: Halogen
- Alkali and alkaline earth are groups of metals.
- Noble gases are least reactive.
- Halogens are the most reactive non metals. Halogen atoms have a high effective nuclear charge that makes them highly electronegative which in turn causes the halogens to become highly reactive elements.
