Symbols of Elements
A 'symbol' is a thing (like a 'sketch' or 'letter',etc.) which represents or stands for something else.When we say 'the symbols of elements',it means 'the symbols of he atoms of the elements' (because elements are made up of atoms). We will first discuss the Dalton's symbols of elements and then the modem symbols of elements.
