About how many elements form all substances?
118 or 94 depending on how you look at it.
The first 94 elements are naturally occurring, and the elements from 95 to 118 are man made in laboratories.
In general, if you have a substance, (and it is not in a laboratory) then it is made of 94 possible elements. However, special man-made substances could, in theory, contain the other elements for a while.

All substances are composed of a relatively small number of chemical elements. There are 118 known elements, but the majority of substances are made up of just a handful of these elements. The most common elements found in substances include hydrogen, oxygen, carbon, nitrogen, and others. However, the exact number of elements that form all substances can vary depending on the specific substance and its chemical composition.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
