some elements do not use their first letters of their English names as their symbols. The symbols for these elements may come from the names of the elements in a different language.
So that the chemical representation of a compound of several elements is more easily recognized, and handled in representations of reactions.
Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.
The elemental symbols used in chemistry are derived from several sources. Some symbols are based on the Latin or Greek names of the elements. For example, the symbol for gold (Au) comes from the Latin word "aurum." Other symbols are derived from the English names of elements, such as the symbol for hydrogen (H). Additionally, some symbols are derived from the discoverer's name or a common property of the element.
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.
Symbols of chemical elements are derived from the chemical name.
Symbols in the periodic table are not based on the names of the elements for several reasons. Firstly, many elements have names that are derived from a different language than English, leading to different initials. Also, some elements have had their names changed over time, making consistency difficult. Lastly, using unique symbols helps to prevent confusion between elements with similar names.
