Question

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 1

Explanation:

Nonmetals increase in reactivity from left to right because nonmetals on the right have more valence electrons. ... - The noble gases break the trend by being less reactive than the elements to their left.
