Dalton’s Symbols of Elements
Dalton was the first scientist to use the symbols to represent elements in a short way. Dalton's symbol for an element represented the 'element' as well as 'one atom' of that element. Some of the symbols of elements given by Dalton are shown below :Element Dalton's symbol Element Dalton’s symbol
Dalton's symbols for elements were difficult to draw and inconvenient to use. So, Dalton's symbols are only of historical importance. They are not used at all.It was J.J. Berzelius of Sweden who proposed that the first letter (or the first letter and another letter) of the name of an element be used as its symbol. This idea led to the modem symbols of elements which are described below.
