Yes, all the elements (natural or artificial) are contained in the periodic (Mendeleev) table of the elements.
I have no idea how to answer that. All the things listed in the periodic table are elements, and there are a lot more than 32 of them.
Carbon , Hydrogen and Oxygen.
It depends on the key of the periodic table. Usually it signifies the type of element, e.g., alkali metals, nonmetal, noble gases, metalloid, rare eath metals, transition metals. However, it can mean other things.

Lanthanide elements
Living things primarily consist of a few main elements (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur), while the periodic table contains over 100 elements. The main elements found in living things make up the bulk of their composition, with other elements present in smaller quantities or roles.
Because it shows all the natural occoring things on earth
Carbon , Hydrogen and Oxygen.
H2O isn't a single element, which is what the periodic table Most things are made of compounds of these elements. . It is comprised of 2 hydrogen atoms (H, on the periodic table) and oxygen (O, on the periodic table).
The periodic table was not 'identified.' It is simply all known elements ordered by similar qualities and atomic number, among other things.

by their atomic number
If your talking about the atomic mass number it is because the amount of neutrons can very. If you are talking about the actual amount of total elements on the periodic table it is because we keep discovering new things.
