Because it is more simple to write one or two letters than a word and also these symbols are valid in all languages.
The chemists' shorthand for elements is called chemical symbols. For example, instead of writing out 'selenium,' it can be quickly written as 'Se.'
Scientist combine the symbols for different elements when they write chemical formulas.
Chemical symbols are representative abbreviations for the names of elements. They are typically one or two letters long and are used to identify elements in the periodic table and chemical formulas.
The symbol and convention describing the electron is e-. In notating an elements electron configuration atomic symbols in brackets are also used to denote them. For example the element of carbon (C) is [He] 2s2 2p. This means C has a helium electron configuration core.
there are lots of chemical symbols about 110 but they are only used for elements not compounds.
Because they are shorter.
No single scientist has devised the symbols of the elements. An organization called the International Union of Pure and Applied Chemistry (IUPAC) has determined the symbols of the elements on the Periodic Table.
Symbols of chemical elements are derived from the chemical name.
Chemical symbols indicate elements.
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.
The chemists' shorthand for elements is called chemical symbols. For example, instead of writing out 'selenium,' it can be quickly written as 'Se.'
The reason is because it is a system that uses letters called chemical symbols, which are a shortned way of writing the names of elements.
Chemical symbols are used to represent elements.
Scientist combine the symbols for different elements when they write chemical formulas.
