All elements get their symbols from their names. The only real rules are that the symbol should be no more than two letters and should be unique; other than that, just about any abbreviation for the name can be used.
In a few cases, the name the symbol is derived from is in a language other than English... usually Latin. This is the reason for symbols like Na, K, Fe, Cu, Ag, Sn, Pb, and others where the letters in the abbreviation may not even appear in the English name of the element.
He is the chemical symbol for Helium. In the periodic table we use the chemical symbols to identify elements easily because some elements have rather long names.
There are NO compounds in the Periodic Table. They are all Elements.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
some of the symbols for elements in the periodic table differ from their names as their syymbols are base on their latin names, for instance, sodium, symbol Na comes from natrium the latin name, same for other elements such as lead (plumbum) and tin (selenium) and so on
Some important questions to ask about the periodic table include: What is the organization of elements based on? How are elements grouped together? What are the properties of elements in the same group or period? How does the periodic table help predict the behavior of elements?
The periodic table lists the elements by their names and atomic symbols. For example, hydrogen is represented by the symbol H, and carbon is represented by the symbol C. Each element has a unique name and corresponding symbol on the periodic table.
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
No element is excluded from the table.
J Q appears in some older periodic tables as 'Unq' (unnilquadium), the temporary name for what is now called Rutherfordium (At. no. 104).

Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
