Why do you have symbols in science?

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.

Why are symbols useful in describing chemicals?

—Symbols are required to make knowledge of studies made useful and easy. —Symbols helps to make equations and other data short and concise. —Symbols enable us to make us write the word quicker and are understood around the world. —Symbols are very useful for scientists as it would take much more time and paper to do their job if they had to write out the full name of every element instead of its symbol. Writing NaCl is much faster than writing Sodium-Chloride.

What are the chemical symbols on the periodic table?

It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used any more. Here's an alphabetical list of element symbols with the corresponding element name. Keep in mind that the names for the elements (and their symbols) may be different in languages other than English.

How does writing equivalent equations help you solve a system of equations?
