Question

A student thinks that halogens are highly reactive because their electrons are weakly attracted to their nuclei. Which is evidence that disputes this student's idea? (2 points)
Halogens react with alkali metals.
Halogens cannot react with noble gases.
Halogens tend to attract electrons when bonding.
Halogens have a full octet of electrons.

Answer 1

I think the correct answer from the choices listed above is the second option. The evidence that would dispute this student's idea would be that halogens cannot react with noble gases. Hope this answers the question. have a nice day.

Answer 2

Answer: Halogens tend to attract electrons when bonding (Option C)

Explanation: Halogens being non metals have greater electronegativities hence, attract electrons and making the statement disputed. Nobel gases are highly stable; this explains why they are nonreactive. They do not form chemical bonds because they only have a little tendency to either gain or lose an electron; on the other hand, halogens are reactive because they only need one additional electron to complete their octet.
