Dalton's atomic theory
In this section let me help you go through on John Dalton atomic theory. Dalton included in his theory some important new concepts. He said that the atoms of any one element are identical in all respects and in particular they have exactly the same mass. Furthermore, different elements have atoms of different mass, the mass of its atoms being a characteristic of each element. Dalton also stated that when chemical combination occurs, small whole numbers of atoms join together.
Except for the slight modification which became necessary when isotopes were discovered, this theory is still accepted today. The various points are, however, more familiar as the basic chemical laws of conservation of mass, constant composition, and multiple proportions.
It was during the third decade of the 19th century that Dalton arrived at his atomic theory. At that time it was virtually impossible to make accurate measurements because the apparatus available was still quite primitive. It is all the more remarkable, therefore, that Dalton's theory has withstood the test of time. This could also help us on probability mass function
Another valuable contribution which Dalton made to chemistry was his idea for representing chemical compounds visually. A distinctive circular symbol was used to denote the atoms of each element – hydrogen was a circle with a dot in the middle, while a circle with one vertical line through it denoted a nitrogen atom.
I hope my information on this topic was helpful to you. Keep reading may be inthe next section let me help you on Geometry in real life.
