Question

Which element is found in Group 17 and is the most reactive non-metal?

  1. Chlorine
  2. Argon
  3. Fluorine
  4. Magnesium

hintHint:

Fluorine is univalent poisonous halogen gas.

The correct answer is: Fluorine


    Fluorine is the most reactive nonmetal as it has the highest electronegativity of all nonmetallic elements in the periodic table. Due to its high electronegativity and small size, fluorine has a strong tendency to accept electrons from other atoms and ions. As a result, it oxidizes all other substances.
