Need Help! What conclusion can be drawn about the number of elements the make up the majority of the world in which we live and the total number of elements identified on the Periodic table?

I think what you're reaching for is how the vast majority of the world we live in is comprised of only a few elements on the periodic table (carbon, hydrogen, oxygen, to name a few).

Explanation:

The other molecules identified on the periodic table do exist in nature but in much smaller quantities than those of a select few atoms.

Of these 118 elements, 94 occur naturally on Earth. Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94.

Explanation:

answer:
