In high school I agree that learning it by heart is unnecessary. Studying chemistry in university though, I agree that the students there should know, at least roughly, where each element is. After all, a lot of reactivity and behavior depends on their period and which group they are in.

I have a PhD in chemistry. It was never expected that we memorize anything. You just take out a periodic table when you need one.
