Thomson had two pieces of evidence:
1- No matter what metal he used for the disk, the particles produced were indentical.
2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom.
These experiments provided the first evidence that atoms are made of even smaller particles.
i have no idea what he enjoyed doing but i think it was his wonderful job working with electrons
The plum pudding model was proposed by J.J. Thomson in 1904, before the discovery of the atomic nucleus. It suggested that atoms were composed of positively charged substance with electrons embedded within it like plums in a pudding. It was later replaced by the Rutherford model when the nucleus was discovered.
to become stable
In the plum pudding model, the overall positive charge was distributed evenly throughout the atom like plums within a pudding, with electrons (negative charges) embedded within the positive charge sphere. This model was later replaced by the nuclear model when it was discovered that the positive charge was concentrated in the nucleus at the center of the atom.
I think you mean what atom only allows a total of 2 electrons and that would be helium.
Thomson thought that the atom must contain positive charges because his discovery of electrons inside the atom indicated the presence of negatively charged particles. To balance the negative charge of electrons, there must be positive charges present within the atom.

J.J. Thomson proposed the existence of small negatively charged particles inside an atom, which he called electrons. This discovery was a crucial development in understanding the structure of atoms and led to the plum pudding model of the atom.
J. J. Thomson
J.J. Thomson proposed the "plum pudding" model of the atom, where electrons were embedded in a positively charged sphere, similar to plums in a pudding. This model suggested that the atom was a uniform, positively charged structure with negatively charged electrons scattered throughout.
I don't think so
Yep i think so
He had around 10 i think.
Thomson described this method. He gave plum pudding model.

You think probable to the discovery of isotopes (with Aston).
the electrons just bounce around the electron clouds freely. think about 2 spheres, a small one suspended inside a bigger one. the smaller one is the nucleus, and the big one is the cloud. the electrons just bounce around in the space between the nucleus and the cloud
