What was Dalton's atomic theory?
Daltons Atomic Theory was: 1) All matter is made of atoms. Atoms are indivisible and uncuttable. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Daltons atomic thory says that all atoms of the same element are alike in mass, colo and size. With the introduction of theory of isotopes the same element can have different mass number with the difference in the number of neutrons ( sub atomic particle ). Thus existence of isotopes contradict Dalton's Atomic theory. : - vineeth
when compairing the two you will realise that the greek theory was very limited, due mainly to the lack of tecknolagy and there scintific outlook on the world being primative and based on elemental factors such as water fire earth wind ex. daltons theary on the other hand was far more complex and based on experamentle data rather then simply reasoning as the greek was. basicaly the greek atom was simple and only theary…
John Dalton was a chemist known for curiosity when it comes to the weather and atmosphere, thus giving birth to his atomic theory. DaltonÕs atomic theory can be divided into 4: Every matter in the world are made of atoms, atoms of an element are similar in properties and mass, a combination of two or more kinds of atoms forms compounds and a rearrangement in atom is called a chemical reaction.
he made a mistake in assuming that the simplest compound of two elements must be binary, formed from atoms of each element in a 1:1 ratio, and his system of atomic weights was not very accurate - he gave oxygen an atomic number of seven instead of eight. Despite these errors, Dalton's theory provided a logical explanation of concepts, and led the way into new fields of experimentation.
Daltons atomic theory changed the way people looked at everything in science,Dalton proved that matter is not able to be broken down past a specific point, (the atom) and that all matter is made up of atoms and now medicine and science have been able to be better, building materials stronger,ect, ect
