Question

where are the most reactive nonmetal elements found on the periodic table?
o at the top of group 17
o at the bottom of group 17
o at the top of group 18
o at the bottom of group 18

Explanation:

• Group 17 elements are halogens (non - metals).
• In a group of non - metals, reactivity decreases down the group. So the most reactive non - metal in group 17 is at the top.
• Group 18 elements are noble gases (unreactive).

Answer:

at the top of group 17
