Concept Introduction:
Every element in the nature has given its own symbol, which is a shorthand method for representing the element. It is an easy way to represent the element by symbol instead of writing out the name of an element. The symbol of the element can be represented by one or two letters. For two letter symbols, only first letter is capitalized. Every element has unique atomic number, symbol and elemental name through which it can be determined. The atomic number of an element is equal to the number of protons present in it.
