Who discovered the indivisible solid sphere model?
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.
Daltons model of an atom is best described as?
Dalton's model of an atom, proposed in the early 19th century, viewed the atom as a solid, indivisible sphere. He believed that atoms of different elements had different masses and sizes, and that they combined in simple whole number ratios to form compounds. However, this model was later replaced by more advanced atomic models that better explained the behavior of atoms.
How did thompsons cathode ray experiment change the atomic model of the day?
Thompson's cathode ray experiment led to the discovery of the electron, which was a fundamental particle in the atom. This challenged the earlier model of the atom as a solid, indivisible sphere by proposing a structure of a positively charged sphere with negatively charged electrons embedded within it. Thompson's model contributed to the development of the modern atomic model.
Description of Solid Sphere Model proposed by John Dalton?
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.
What evidence better support the solid sphere model or the plum pudding model?
The Bohr model is accepted today - of course, with some refinements.

How did Thompson's model differ from Daltons model?
Thompson's model proposed that atoms were made up of positive and negative charges distributed throughout a positively charged sphere, similar to a raisin pudding. In contrast, Dalton's model suggested that atoms were indivisible and uniform spheres with no internal structure. Thompson's model introduced the idea of subatomic particles, while Dalton's model viewed atoms as simple building blocks of matter.
Which item best represents Dalton mental image of an atom?
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.
What is the difference brtween Dalton's model of an atom and the modern model of an atom?
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.
When was the Small Spherical Solid Indivisible model developed?
The small spherical solid indivisible model, also known as the atomic theory, was developed in the 5th century BC by the ancient Greek philosopher Democritus. He proposed that all matter is made up of tiny, indivisible particles called atoms.
Model of earth?
Ball, globe, or sphere.
