He was the first to introduce the idea that matter is made up of indivisible basic elements, called "atoms."
-
He postulated that matter is made up of very small particles called atoms, which are indivisible and cannot be destroyed. Atoms of the same element are equal to each other, have the same mass and equal properties.
-
It is a theory about atomic structure; The atom is composed of negatively charged electrons in a positive atom, embedded in it as well as raisins in a pudding.
-
He found that cathode rays deposited charge on an electroscope, confirming that they were charged particles.
-
He postulated that the mass of the atom was concentrated in a small region in the scepter and in its crust electrons were found spinning around the center.
-
He proposed a atomic model where the electrons they revolve around core in levels well defined.
-
He modified Bohr's model, said electrons could also rotate in more complex elliptical orbits.
-
He proposed a atomic model where the electrons they revolve around core in levels well defined.
-
Model based on the Principle of uncertainty (It is impossible to determine the speed and position of a electron instantly)
