I've been trying for five minutes now to permute this into a question that actually makes sense, and this is the best I can come up with:
Sometimes, people use unofficial abbreviations, like "D" for deuterium or "Ph" for a phenolic group or "OAc" for acetate (particularly confusing one, that, as Ac is the symbol for actinium).
These don't appear on the Periodic Table because they aren't actually elements. Deuterium is an isotope of hydrogen, and the other two are polyatomic.
If that doesn't answer what you were trying to ask, please be a little more clear what symbols in particular you're talking about.

Symbols are used to shorten the names of the elements.

Symbols are the short forms to represent elements. Each element will have a unique symbol.
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.

Symbols of elements areEnglish or latinwords or roots.
Symbols are used to shorten the names of the elements.
The Periodic Table only displays elements. The symbols for the elements are emphasised because that is the most important item of information in the table. Other information, such as atomic weight, etc., are given less emphasis.
The letters on the periodic table are the chemical symbols of the chemical elements.

All elements appear in the periodic table, there are more than 100 of them, so please look at the related link below to see an example of such table and all symbols of them.(Please note that there is no special group of 'periodic' elements)
It is filled with the names (or chemical symbols) of elements.
