Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of chemistry but also initiated its progression into a modern science.
In 1869 Dmitri Mendeleev discovered that the properties of elements "were periodic functions of the their atomic weights.” This later on became known as the “Periodic Law.” At his funeral
