Most elements have symbols from the Latin or Greek language. Often synthetic Latin or Greek words as the element was not known to them. It is usually chance that the symbols correspond to English.

Why do some elements start with a different letter on the periodic table?
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
Is each element is abbreviated by a one- two-letter formula True?
A quick look at my Periodic Table shows that elements 1 through 111 have either 1 or 2 letters, but elements 112-118 have 3 letter chemical symbols.
What does PA stand for in the periodic table?
No such symbol as 'PA' on the Periodic Table. However I think you mean 'Pa' Protactinium'. 'P' could be the element phosphorus, but there is no element with the letter 'A'. NB When writing up chemical symbols remember the rules;- #1 Single letter elements , always have a CAPITAL letter. #2 Two letter elements, always have a capital letter to start and the second letter is ALWAYS small case. Here are some examples. H - Hydrogen , O - Oxygen N - Nitrogen Na - Sodium (Nadium) Cu - Copper (Cuprum) Cl - Chlorine If you do not correctly write the chemical symbol, there could be confusion as to what substance is being referred . e.g. 'CO' - Carbon Monoxide and 'Co' - Cobalt.
What does the symbal OH stand for on the periodic table?
What is 'oh' ? If you mean 'OH' , This is the hydroxide anion and is correctly written as 'OH^-' , because it is a charged species. The hydroxide anion is composed of 1 x oxygen and 1 x hydrogen atoms and 1 x excess electron. You will find Hydrogen (H) and Oxygen(O) separately on the Periodic Table. Also when writing up chemical symbols, please follow the following rules ; - #1 Single letter elements ALWAYS have a capital letter . #2 Two letter elements have a capital to start and ALWAYS a small case letter as the second letter. These are the international standard, followed world-wide. Oh!!!! 'oh' does not mean anything chemically.
Why are there a few elements that have 3 letter symbols?
scientists haven't figured out that element.
How many elements have two letters in their symbol?
99 elements have been identified and named and given 2 letter symbols. 13 elements have 1 letter symbols. Additional elements have been theorized, but not synthesized or named, and have 3 letter symbols. See Wikipedia Periodic Tables, linked.
What does 'k' stand for in the periodic table?
'K' in the periodic table is the symbol for potassium . Its Latin name being 'Kalium' , hence the symbol 'K'. NB. One letter elemental symbols are ALWAYS a CAPITAL letter. NOT small case 'k'. Two letter elemental symbols have first letter a capital letter and the second letter as lower/small case. e.g. 'Na' Sodium (Nadium).
What are the chemical symbols on the periodic table?
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used any more. Here's an alphabetical list of element symbols with the corresponding element name. Keep in mind that the names for the elements (and their symbols) may be different in languages other than English.
What are the similiarities of all the symbols on the periodic table of elements?
In the case of symbols, the first letter will be capitalized. Other that than there is no general similarity and each element has different symbol.
What are the symbols for the elements in the periodic table?
If you look at the periodic table (go to webelements.com to see one if you dont have one) the symbol is the letter or two in the middle of each square. For example, the symbol for Hydrogen is "H", the symbol for Potassium is "K", the symbol for neon is "Ne" & The symbol for Carbon is "C". The symbol is always one or two letters, except for the last few elements, which for now have 3, until they get real names.
Why do symbols on the periodic table have two letters?
Not all elements have two-letter abbreviations; some, like hydrogen (H), carbon (C) or potassium (K) have a single letter symbol.
Why do some elements start with a different letter on the periodic table?
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
How are element names shortened?
Elements are abbreviated by one or two letters, and not always the first letter or two in the word. The abbreviations for all elements can be found on the periodic table of elements.

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.
What is an element's 'symbol'?
element symbols are abbreviation of elements name like gold's symbol is Au. always first letter is cap. and second is lowered i hope this helped you.
