Which is the most reactive non-metal in the periodic table?
AFluorine
BOxygen
CChlorine
DNitrogen
Answer & Solution
Correct answer: A. Fluorine
1. Non-metallic reactivity peaks in the top right of the periodic table.
2. Fluorine sits in period 2 of Group 17 (halogens).
3. It has the smallest atomic size in Group 17.
4. Smaller size means a stronger pull on incoming electrons.
5. So fluorine has the highest electron-attracting ability of all non-metals.
6. This makes fluorine the most reactive non-metal.
