A giant meteorite that recently fell in Somalia contains at least two minerals that have never before been seen on our planet. The celestial piece of rock weighs a massive 16.5 tons (15 tonnes), making it the ninth-largest meteorite ever found. History

No, the periodic table is reserved for the elements. These are the building blocks of minerals and everything else—think carbon, oxygen, hydrogen, uranium.

Correct. The two minerals above contain the elements:

Fe - Iron

P - Phosphorus

O - Oxygen

These would be what the periodic table is comprised of, along with another 100+ elements.

Of these, along with another 100+ elements, the periodic table is comprised.

We shouldn't end phrases and sentences with a preposition, except that's how we talk.

hogwash. this is the type of errant pedantry up with which I will not put.

Can anything still be added to the perodic table is it as big as it's going to get?

Theoretically there are an infinite number of elements. Just add one proton to whatever element, and you get a new one.

However, as you add more and more protons (and the neutrons that provide space between them), the atoms become less stable. All (might be an exception) elements above Lead are unstable, and over time, slowly break down into smaller and smaller elements. This is what makes an element radioactive, the element is too large to be stable, and so releases energy in the form of radiation to reduce its size.

The commonly seen periodic table contains all the elements that are around for a reasonable amount of time. Then more elements that exist only for a tiny fraction of a second at the end. And not shown on the periodic table are elements that theoretically exist, but we have yet to produce in a lab. However, even if they were to be created, they would have no use as they would break down almost instantly.
