Chemical symbol Totally Explained

Everything about Chemical Symbols totally explained

:See also chemical formula. A chemical symbol is an abbreviation or short representation of the name of a chemical element, generally assigned in relation to its Latin name. Natural elements all have symbols of one or two letters; some man-made elements have temporary symbols of three letters.
   Chemical symbols are listed in the periodic table and are used as shorthand and in chemical equations, for example, ť 2H₂ + O₂ → 2H₂O

Because chemical symbols are often derived from the Latin or Greek name of the element, they may not bear much similarity to the common English name, for example, Na for sodium (Latin natrium) and Au for gold (Latin aurum).
   In China, each chemical element is assigned an ideograph as its symbol; most of them have been explicitly created for this purpose (see Chinese characters for chemical elements).
   Chemical symbols may also be changed to show if one particular isotope of an atom that's specified, as well as to show other attributes such as ionization and oxidation state of a chemical compound. Attached subscripts or superscripts specifying a nucleotide or molecule have the following meanings and positions:

The nucleon number (mass number) is shown in the left superscript position (for example, ¹⁴N)
The number of atoms of a nucleotide is shown in the right subscript position (for example, N₂)
The proton number (atomic number) may be indicated in the left subscript position (for example, ₆₄Gd)
If necessary, a state of ionization or an excited state may be indicated in the right superscript position (for example, state of ionization Na⁺⁾
