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.

No, he is not correct. Xenon is not very reactive since it is located in the group of noble gases. The noble gases are all chemically unreactive gases.Elements within different groups within the periodic table have different physical and chemical properties. Hope this answers the question.

We can’t you if you only tell us that you have to show us what the answers are

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
