Lorenzo is making a prediction. “I learned that nonmetals increase in reactivity when moving from left to right. So I predict that xenon will be more reactive than iodine.” Is Lorenzo correct? If so, why? If not, explain his error.

Answer:

Lorenzo is not correct. Nonmetals increase in reactivity from left to right because nonmetals on the right have more valence electrons. They need to gain fewer electrons to have a full outer shell. However, this trend only continues until group 17, because the noble gases already have a full outer shell. Therefore, their reactivity is the least of all the elements.

What did you include in your response? Check all that apply.

A
Nonmetals on the right need to gain fewer electrons to form an ion, so they are more reactive.
B
The noble gases already have a full outer shell.
C
The noble gases break the trend by being less reactive than the elements to their left.
