Whats the word for when something like an issue goes to far

Going overboard, excessive, overabundant, to the extreme, overdone?

The answers are very vague but basically the nonmetal group would be anything but the middle —

So the nonmetals would be the first , second group and then the last group, second to last group, all the way until you see B for Boron. Anything in the middle of the periodic table is a metal. So I would say along the top but to note, there are particular elements in group that aren’t along the top of the periodic table that would be considered a nonmetal!

I hope this helps you and if you are still confused let me know! :)
