If I were to mix every chemical from the periodic table and then drank it would I die

yes

All substances have toxicity levels. The common phrases are that even water and oxygen become toxic at high levels.

In your question, you haven't given any amount. If it were possible for you to ingest a single atom of each chemical, you'd be fine. You ingest microscopic amounts of very toxic materials every day. A few more atoms would be in the noise.

But even a few micrograms of plutonium would be bad. If you're talking realistic amounts, then yes it would be extremely toxic.

Noooooooooooooo.

This is such a good and not common sense question (seeing as some elements on their own can kill you even just by being near them much less all of the elements together) I think you should give it a shot and let us all know how it goes.

Yes, probably.

yes. It would also be impossible to make.

probably die just from being in the same area as the mixture

yes
