(i) All mater is composed of atoms.
(ii) Atoms cannot be created, divided or destroyed.
(iii) All the atoms of one element are alike, and different from these of any other element.
(iv) Atoms combine together in the ratio of small whole numbers.

In which of the following sets of atomic numbers, all elements are in the same group-

Which of the following laws of chemical combinations cannot be explained by Dalton's atomic theroy?

In which of the following sets of atomic numbers, all the elements do not belong to the same group?

All atoms of an element differ from each other.

Dalton's atomic theory successfully explained. (i) Law of conservation of mass (ii) Law of constant composition (iii) Law of radioactivity (iv) Law of multiple proportion

Dalton's atomic theory successfully explained. (i) Law of conservation of mass (ii) Law of constant composition (iii) Law of radioactivity (iv) Law of multiple proportion

According to Dalton's atomic theory, all matter whether an element, a compound or a mixture is composed of small particles called atoms which can neither be created nor destroyed during a chemical reaction. Dalton's theory provides a simple explanation for the laws of chemical combination. He used his theory to explain law of conservation of masses, law of constant proportions and law of multiple proportions, based on various postulates of the theory. Dalton was the first scientist to use the symbols for the elements in a very specific sense. When he used a symbol for an element he also meant a definite quantity of that element, that is one atom of that element. Which postulate of Dalton's atomic theory explains law of definite proportions?
