It was a cool looking greek letter.
The 'symbol' is a letter in the Greek alphabet - which is pronounced 'pi'. The connection between the letter and the ratio of the diameter and the circumference fo a circle may come from the fact that the letter pi is the first letter of the Greek word for perimeter, and the word for periphery.
The symbol for pi (π), is the Greek letter that is the equivalent to the Roman p. It is the Greek letter pi. It is the first letter of the Greek word περίμετρος (perimetros) from which our word perimeter comes.
The symbol of pi is 16th letter of the Greek alphabet and it was chosen because the first letter of the equivalent of the word perimeter begins with pi in the Greek language.
The ancient Greeks did the original work of inventing geometry as we know it, and pi is a letter in the Greek alphabet, so it was a convenient symbol for them to use.
The first letter is always capitalized, and the second letter is always lower case.
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.
The first figure in a properly written chemical symbol represents the atomic number of the element, which is the number of protons in the nucleus of an atom. The atomic number defines the element's identity and determines its unique chemical properties.
The chemical symbol of a chemical element is derived fom the his name: the first letter or the first two letters.
When a symbol contains two letters, the first letter indicates the element's chemical symbol, while the second letter is always lowercase. This convention helps differentiate the symbol from potential elements with similar first letters.
V was picked for Vanadium's chemical symbol because it is easy to remember a symbol if it is the first letter of the element's name. Sometimes the symbol is the first letter of the element's name in Latin.
W, which is the first letter of its older name, which is wolfram.

The chemical symbol of hassium is formed from the first and the third letter of his name - Hs.
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.
This depends on the type of compound. For metallic compounds, the metal comes first. For nonmetallic inorganic compounds the more electropositive element comes first. For MOST organic compounds, carbon comes first.
The chemical symbol of an element is written using the one or two letter abbreviation of its name. The first letter is always capitalized, and if a second letter is used, it is in lowercase.
