May you elaborate so I have context?

At least one atom of every element has existed on Earth at one point or another by some circumstances. All the natural elements only have been catalogued because they have been found on Earth. All the manmade elements were made on Earth, and there had to exist at least one atom of them for them to be catalogued.

Aren't there some that are not natural but are known to be possible to exist due to science brains knowing how atoms work but have yet to be synthesized

There are placeholders for those until we figure out how to make them. I don't think they get named until they're actually made.

They're on the periodic table, yes?

The extended periodic table has placeholders for them. They have temporary names

The periodic table is "complete", in that there are no longer any holes. Astatine, the last element that can naturally exist to be discovered (element 85) was discovered in the early 40s. It has a half life of just over 8 hours, only exists as an intermediate in the radioactive decay of several heavier elements, and it is estimated that there is less than a gram of it in the earth's crust at any given moment. Very few periodic tables show row 8, and every element in the first 7 rows have been discovered/synthesized, so most are actually complete.
