The Solid Sphere Model proposed by John Dalton suggests that an atom is a solid sphere with no internal structure. Dalton envisioned atoms as indivisible and indestructible particles that make up all matter. This model laid the foundation for modern atomic theory.
the indivisible solid sphere was invented in 1803 by John Dalton
Dalton theorized that an atom was a tiny solid sphere. Today we know that atoms are not solid, in fact are mostly open space.
dalton created a solid sphere model. He belived that the atom was one single sphere, and that diffrent elements were made of diffrent types of atoms.
The indivisible solid sphere model, also known as the billiard ball model of the atom, was proposed by John Dalton in the early 19th century. He suggested that atoms are indivisible spheres that make up all matter and that they combine in simple whole number ratios to form compounds.
Dalton's mental image of an atom can be best represented by a solid, indivisible sphere with no internal structure, similar to a billiard ball. This model suggested that atoms were the smallest, fundamental particles of matter.
I think it probably looked like a sphere. not positive.
J.J. Thomson's discovery of the electron showed that atoms were not indivisible as Dalton thought, but were made up of smaller subatomic particles. This led to the development of the plum pudding model of the atom, which replaced Dalton's solid indivisible atom theory.
Since a sphere is round it is a shape without a face.
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all matter.
John Dalton concluded that gases were made up of solid particles with empty spaces between them. This idea helped contribute to the development of the atomic theory of matter.
No it is not a solid.
