How many letter symbols can an element have?
Most elements have either 1 or 2 letters but some elements such as Ununpentium, have 3 (Uup)
Of the first 103 elements how many have two letters in their symbols?
Not all elements can be identified by a single letter. For example, Carbon (C) and Chlorine (Cl) both start with a "C" and have "C"'s in their symbols. Another letter had to be added to distinguish the two. Also, the Periodic Table has over 100 elements and there would not be enough letters to cover them all if they were only single letters.
Why some symbols- for example cal and si- have two letters?
Becasue there are only 26 letters of the [Roman] alphabet and more than 4 times that number of elements.
Why do the symbols for some elements such iron seem to have no relationship to their name?
The symbols of such elements are based on their Latin names. For example, the symbol Fe for iron comes from the Latin ferrum, meaning iron.
What are the symbols of the elements named after planets?
See link. It has all the symbols for all the planets.
Why do some element have unusual letter for their symbols?
some elements do not use their first letters of their English names as their symbols. The symbols for these elements may come from the names of the elements in a different language.
Why do some symbols have one letter some have two letters and some have three letters?
Symbols in science, such as those representing elements, often have one- or two-letter symbols to make them easier to write and work with. Some elements have symbols derived from their Latin names, resulting in two-letter symbols. In cases where two elements have the same first letter, the second letter is used to differentiate them.

Why did some elements have symbols which did not started with his first word?
most of these use the letters from the Latin name. in fact most element symbols come from Latin words not English, even when the letters are the same.

How are the letters in a Periodic Table chosen?
some elements have their symbols directly from their names. Eg: oxygen-O,nitrogen-N some get symbols from their latin names. eg: Potassium-K from Kalium (Latin for potassium)
Are there graphic symbols for the chemical elements?
Chemical symbols are these days given 1-, 2- or 3-letter symbols based on some letters in their name or name in Latin. For example H is Hydrogen, Ca is calcium and Uuo is Ununoctium. Or, from the Latin names, Fe is Iron, K is Potassium and Ag is Silver. It appears that different symbols were used in the past, rather like diagrams that are used for the planets or male and female symbols.

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.
