The symbols for chemical elements used today were proposed by the Swedish chemist Berzelius in 1814.
Elements
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.
There are mainly three ways of making symbols :1.By using the first letter of the name of the elements.2.If the name of two or more elements begins with the same letter,the second letter of their name is also taken with first letter.3.Symbols are made by using the letters of the name of elements in other languages also.

designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's Latin name.
In 1952, the designation or code letter on a Georgia license plate for a pickup truck was A/p.
R=Romeo
That's the two-letter designation for Ireland.
A sample letter informing a change in designation can be found in many templates online. The sample letter will explain the job change and be formally address to the current supervisor and the new supervisor.
The Greek letter designation is a Greek letter followed but the possessive form of the constellation name (for example, alpha-Orionus). In most cases (Ursa Major being a notable exception), the brightest star in a constellation designated with the Greek letter alpha, the second-brightest with the Greek letter beta, and so on. Thus the Greek letter designation gives information about both relative brightness and location. There is no connection between the Greek letter designation and ancient Arabic names.
Alphard is the brightest star in the constellation Hydra.It's designation or letter is Alpha Hydrae
Assuming you mean the international radio designation for the letter 'K' - it is Kilo.
