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

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.

t was already answerd i just wanted to answer too

Answer 2

Lorenzo is not correct because xenon is a noble gas which is nonreactive or inert.

Step-by-step explanation:

The reactivity of nonmetals increases when moving from left to right in the periodic table. They have a high attraction for electrons and tend to gain electrons. The most reactive nonmetal element is fluorine. Noble gases are the least reactive because they have the most stable arrangement of electrons (eight valence electrons). So they rarely react with other elements. So the prediction that xenon will be more reactive than iodine is incorrect.
