There are 14 elements with a one letter symbol. However, only 12 of them also start with that letter. They are Hydrogen, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Phosphorus, Sulfur, Yytrium, Vanadium, Uranium, and Iodine.

Why do some elements have a symbol with two letters?
Since there are only 26 letters in the alphabet and there are (currently) 111 known elements, therefore not every element can be represented by only 1 letter. Also some elements date back to antiquity and already have symbol names assigned by Alchemists, for instance, rather than being G, gold is Au for the Latin word aurum for shining dawn.

What is a FIFO array?
It means that elements are fetched from the array in the same order they arrive - first in, first out (FIFO). Also called a queue.

How are symbols and names chosen for elements?
The name of an element depends on who discovered the element and when. Often the names have roots in other languages such as Greek or Latin. Some elements are named after the person who discovered the element or also after other famous scientists to honor that person. For many elements, the symbol is just the first letter (or first two letters) of the name of the element. Note that the symbol for some elements is taken from the name in another language (Greek and Latin origins quite common) and is not the first two letters of the element's name in English. See the Web Links for information about each elements' name! Click on any element in the periodic table and scroll down to see how and why it was named that way. Some examples: hydrogen, symbol H, is from the Greek words hudôr (water) and gennan (generate) oxygen, symbol, O, is from the Greek words oxus (acid) and gennan (generate) carbon, symbol C, is from the Latin carbo (coal) lead, symbol Pb, is for plumbum, which is "lead" in Latin gold, symbol Au, is for aurum, which is "gold" in Latin iron, symbol Fe, is for ferrum, which is "iron" in Latin silver, symbol Ag, is for argentum, which is "silver" in Latin mercury, symbol Hg, is for hydrargyrum, which is for "liquid silver" in Latin polonium, symbol Po, is named after Poland, the home country of Marie and Pierre Curie, the people who discovered it curium, symbol Cm, after Pierre and Marie Curie for their contributions to chemistry (Curium was discovered by G. T. Seaborg) lawrencium, symbol Lr, after Ernest Lawrence beryllium, symbol B, after Berylli, California where much research was done on discovering new elements

Does calcium contain carbon?
No, this is a misunderstanding of what chemical symbols mean. Some elements, like carbon, have single letter symbols (C in this case). However, there are far more than 26 elements, so we also have to use two letter symbols, such as Ca for calcium. It is vital to remember that the large and the small letter together form just ONE symbol. So, a symbol is either a capital letter, or a capital and a lower case letter which can't be split. An example of the difference is CO and Co. CO is a molecule of carbon monoxide, composed of a carbon atom joined to an oxygen atom. Co is a single atom of cobalt.

Why must some element symbols have two letters instead of just one?
The reason why some element symbols have two letters instead of one is that some elements start with the same letter. It would be very difficult to distinguish elements if two both had the same symbol. For example, Carbon and Calcium both start with the letter "C", but Calcium's symbol is "Ca". Also, some, like Iron's "Fe", were named a long time ago, and chemists had different names for them.
Why is the symbol of Celsius written in capital?
Just like the Fahrenheit symbol, both scales were named after their inventors, Anders Celsius and Daniel Fahrenheit. It became custom to simply use the first letter of their last names as the symbol for the scale. Since everyone capitalizes their initials and their names, the symbols for the scales are capitalized also.
