What did JJ Thomson think the atom looked like?
Thomson’s Atomic Model- Postulates
Thomson’s atomic model resembles
a spherical plum pudding as well as a watermelon
. It resembles a plum pudding because the electrons in the model look like the dry fruits embedded in a sphere of positive charge just like a spherical plum pudding.

What did Werner Heisenberg discover?
Werner Heisenberg discovered
the uncertainty principle
, which states that the position and the momentum of an object cannot both be known exactly.
Why did Chadwick use paraffin wax?
Chadwick felt that
the radiation could not be γ rays
. The α particles could not provide enough energy to do this. He thought the beryllium rays were neutrons. … In the path of the rays, Chadwick put a paraffin target.
Did James Chadwick win Nobel Prize?

Did Ernest Rutherford discover the proton?
In 1919 Rutherford had discovered
the proton, a positively charged particle within the atom’s nucleus. … Rutherford also put out the idea that there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron.

The electrons in the atom must be orbiting around this central core, like planets around the sun,
Rutherford
proposed. Rutherford carried out a fairly simple calculation to find the size of the nucleus, and found it to be only about 1/100,000 the size of the atom. The atom was mostly empty space.

a model of the atom in which the electron was able to occupy only certain orbits around the nucleus
. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus.
