The periodic table a tabular arrangement of the chemical elements has proved its applicability and so do the symbols of elements which have been carefully selected through time. There is no need to change a”winning team”.
These are old symbols for "old" elements based upon the Latin language: aurum for gold, argentum for silver, stibium for antimony, and ferrum for iron. This also applies to natrium for sodium, cuprum for copper, hydrargyrum for mercury...etc.
The use of these symbols is spread worldwide with nearly complete agreement of scientists. I agree with Professor Herald G. Dill that there is no need for changing.
Elements have been named on the basis of names of cities, countries, scientists, mythological considerations and in the language of the region where they were discovered. Now, we are mostly following English as medium of teaching- learning , research and in developing learning materials such as textbooks,videos. It could have made remembering the symbols somewhat easier ,had they been related with English names such as iron ,mercury.However, as every society has great concern for name and fame, it is not a big deal in retaining these names and symbols . I also do not want any change.
