Why do scientists use chemical symbols rather than words to represent a compound or element?

Answer 1

The symbols (formulas) show the elements or ions in a compound. Sometimes it is easier to see the relationships between the elements with an empirical formula. But with larger molecules with atoms in complex arrangements, the written names are sometimes more appropriate. (e.g. sodium benzoate NaC7H5O2 which is formed from an ion of benzene C6H6)

Answer 2

Symbols are an efficient means of conveying certain types of information which would otherwise be much more difficult to write. For example, a two letter symbol of a chemical element is much more convenient, when you are writing chemical formulas or equations, than writing out the full names of the elements.

Answer 3

To save time writing. They are abbreviations, no different to writing US for United States.

Answer 4

They use symbols so that it is easier and quicker and shorter to write scientific names, since so many of them are really long.

Answer 5

to minimize the time
