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.
Did Dalton's model of the atom include protons?
no, because according to him an atom is a tiny indestructable sphere with mass on it.
Did Dalton model of the atoms include protons neutrons and electrons inside the atom?
no, because according to him an atom is a tiny indestructable sphere with mass on it.
What is the billiard ball model?
The billiard ball model is a simplified representation of gas molecules as hard spheres that move randomly and collide like billiard balls. In this model, gas molecules are assumed to have negligible volume and attraction, allowing for simple calculations of pressure, volume, and temperature based on the kinetic theory of gases.
What most accurately represents John Dalton's model of the atom?
John Dalton's model of the atom, proposed in the early 19th century, suggested that atoms were indivisible and indestructible spheres. He also proposed that elements consist of only one type of atom that combines in simple whole-number ratios to form compounds. However, we now know that atoms are composed of subatomic particles and are not indivisible.

Did Dalton's model of the atom include protons?
no, because according to him an atom is a tiny indestructable sphere with mass on it.
Did John Dalton's model of the atom look like a tiny solid sphere with a predictable mass for a given element?
I think it probably looked like a sphere. not positive.
How Dalton crookes thomsont Rutherford showed the early model of the atom?
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.
Did Dalton model of the atoms include protons neutrons and electrons inside the atom?
no, because according to him an atom is a tiny indestructable sphere with mass on it.
Did Dalton believe that the atom was a hard sphere throughout?
John Dalton initially proposed that atoms were hard, indivisible spheres in his atomic theory developed in the early 19th century. However, as scientific understanding advanced, Dalton's model was refined, and later discoveries revealed that atoms are composed of smaller particles (protons, neutrons, and electrons) and have complex structures. Thus, while Dalton's early concept was of a hard sphere, it evolved as new information emerged.
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.

Who hypothesized that the atom was a tiny hard sphere?
The concept of the atom as a tiny hard sphere was primarily proposed by John Dalton in the early 19th century. Dalton's atomic theory, presented in 1803, suggested that elements consist of indivisible particles called atoms, which combine in fixed ratios to form compounds. His model laid the groundwork for modern chemistry by introducing the idea of atoms as fundamental building blocks of matter.
Who made a model of electrons surrounding the nucleus at a distance?
Dalton proposed planetary model. He kept electrons at a distance.
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 is Thomson model different from the previous model?
The Thomson model, also known as the "plum pudding model," proposed that atoms are composed of a positively charged "soup" in which negatively charged electrons are embedded, resembling plums in a pudding. This contrasted with previous models, like Dalton's solid sphere model, which viewed atoms as indivisible and solid spheres. Thomson's model was revolutionary as it introduced the idea of internal structure within the atom, but it was later replaced by the Rutherford model, which proposed a nucleus at the center, surrounded by orbiting electrons.
