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.
There is no 1st 2nd 3rd 4th pattern to the symbols of the elements. The goal was to produce short (i.e. one or two letter) abbreviations without duplicating an already existing one. In some cases that results in the second letter of the abbreviation being from fairly far along in the element's name. Some elements get their symbol from other languages. Gold, for example is Au, from the latin word for gold, aurum. Most of the symbols were based on a need for them to not be accidentally confused with another element. At the time of most of the elements discovery, notes were hand written not typed and so H (hydrogen), He (helium) and Hf (hafnium) all had to look unique so there would be no mistakes.
In those cases, the English word for the element is not necessarily the same as the original word used to form the symbol for it. For example, the symbol for Iron is Fe because the latin word for it is Ferrum, which is the word at the base of that symbol.
Some of the elements are not named in English. This is especially true for elements known in ancient times. For example, lead is given the symbol Pl for its Latin name plumbium. Since lead was widely used in Roman pipes this gives you a clue where the word plumber comes from.
To distinguish between elements that start with the same letter. For example, Carbon, Chlorine and Calcium all start with the same letter - their chemical symbols are C, Ch and Cl respectively. It would be extremely confusing to label different chemicals with the same initial letter !
The symbols for elements have either one or two letters. If there are two letters, the first one is capitalized and the second one is not.
They are the symbols for the elements . Often they are some of the letters of the English name.For example, Si means Silicon. Silver cannot be Si as well. Therefore, we use the Latin translation, Argentium, to create Ag.
It has two capital letters, and is the abbreviation for the state of California. Elements that have two letters (like Pb for lead, Fe for iron) only have one capital letter.
The term for the abbreviation is the "symbol" (aka elemental symbol or atomic symbol) for the element. The letter may not be the actual first two letters, and for some elements it is based on older names (e.g. Au for gold is from the Latin name aurum and Pb for lead from plumbum).
The chemical symbol of an element represents the abbreviated name of this chemical element.Example: the chemical symbol for lead is (Pb) because the Latin language name is plumbum.the symbol Cl represents chlorine in the periodic table
The symbols for elements have either one or two letters. If there are two letters, the first one is capitalized and the second one is not.
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.
Every element recognized so far has a unique symbol in the periodic table. Some has one letter in their symbol, where many have two letters. A set of recently discovered elements using nuclear fission reactions have three.

A chemical symbol for an element is one or two letters. These are found on the Periodic Table of elements. The chemical symbol is an abbreviation of the chemical element name.Example: O is the chemical symbol for Oxygen.K is the chemical symbol for Potassium.Pb is the symbol for lead.He is the symbol for helium.
Not all elements have two-letter abbreviations; some, like hydrogen (H), carbon (C) or potassium (K) have a single letter symbol.
When you say, "chemical symbol," I assume you mean the symbol for an element as used in the formula of a compound.Quite simply, there are well over 100 elements and only 26 letters, so we just plane ran out of letters.
While giving symbols to the elements the first letter of the name of the element was used. But in case of two or more elements with same initial the next elements were given symbols containing first two letters. Since boron has symbol B, so bromine got the symbol Br.

Not always... There are chemical elements beginning with the same letter - for example Copper and Cobalt. However - every chemical symbol does consist of two letters.
