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 do you thinks so?

Lorenzo is not correct

Explanation:

Eventhough Xenon is to the right of Iodine in the periodic table, Lorenzo isn't correct.

Xenon is a noble gas.

They aren't reactive.

Xenon falls in the "group" of noble gases in the periodic table.

Elements withim different groups in the periodic table have different physical and chemical properties.

So, Lorenzo's prediction is wrong.
