If humans depleted Earth of an element entirely, would that element be removed from the periodic table?

Since there is a helium shortage, let's use that as an example. If we entirely used up all of the helium available on the planet, would we keep helium on the periodic table or would we remove it due to it no longer existing naturally on the planet?

    Funny thing is that helium wasn;t first discovered on Earth, it was discovered in the Sun.

    No, helium would STAY on the periodic table. Helium was discovered on the Sun BEFORE it was discovered on Earth through spectroscopy.

    Helium is a nice example because prior to 1868 no one on earth had a clue it existed. A spectrograph of the sun detected an element there that was not known to exist on the earth and it was named after the Greek word for the sun (Helios) and called Helium. It was not until 1895 that Helium was actually isolated and confirmed to exist.

    Based on the fact the place on the periodic table was reserved before the actual confirmation of the existence of Helium I would suggest that it would remain on the table.

    As for depletion, at one time helium was only recovered from deep caverns. But like other gases it can be separated from air by a long process. It was a national defense item at one time. It was also illegal to sell Germans Helium before WWII. Argon has taken the place of Helium in some commercial operations (welding and other times an inert atmosphere is desired).

    Nope. We had spaces allocated for elements in the periodic table that we hadn't found yet but based on the periodic table we knew/believed existed.

    i think we would definitely keep those elements, as their properties could probably still be used to figure out things with other elements.

    Some elements are only stable for nanoseconds. But they're still elements.

    No, there are already all sorts of elements in the periodic table that do not occur naturally.

    The periodic table is not intended to be an inventory of terrestrial elements.

      with atomic numbers greater than 99 do not exist now unless CERN or some such physics lab is in the middle of an experiment to make them this very moment. And even then they will be gone again before the week is up.)
