John Dalton
J.J.Thomson was a physicist. He is credited with discovery of the electron based on his work with the cathode ray. He essential established the first sub-atomic particle.
The solid sphere model suggests that an atom is little more than a singular, solid particle without other components.
John Dalton's model of the atom is accurately represented by solid spheres. These look like tiny snooker balls. He noticed that elements are combined in definite whole number ratios.

I suupose that this assertion is not correct.
the indivisible solid sphere was invented in 1803 by John Dalton
it was developed in 410 B.C.

Sphere
It was commonly described as a Solid sphere

A sphere is the best choice.
Dalton's model of the atom was an indivisible solid sphere. We now know that most of the atom is empty space, and that atoms have a dense positively charged nucleus that contains protons and usually neutrons, and that the negatively charged electrons are found outside of the nucleus in an electron cloud composed of energy levels.
The Bohr model is accepted today - of course, with some refinements.
Since a sphere is round it is a shape without a face.
No it is not a solid.
