Question

which group on the periodic table has the most reactive non - metals?
alkali metals
halogens
noble gases
alkaline earth metals

Explanation:

• Alkali Metals: These are reactive metals, not non - metals.
• Halogens: They are non - metals. Halogens have 7 valence electrons and need only 1 more electron to complete their octet. This makes them highly reactive as they readily gain an electron.
• Noble Gases: They have a complete octet (except helium which has a duet). They are very stable and unreactive.
• Alkaline Earth Metals: These are reactive metals, not non - metals.

Answer:

B. Halogens
