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 jj Thomson discover?
J.J. Thomson discovered the electron, a subatomic particle found in all atoms. This discovery led to his development of the plum pudding model of the atom, which revolutionized our understanding of atomic structure.
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.
In which model are atoms are imagin as tiny balls?
Atoms are imagined as tiny balls in the billiard ball model or Dalton's atomic theory. This model suggests that atoms are indivisible, solid particles with no internal structure.
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.
Who came up with the indivisible solid sphere?
the indivisible solid sphere was invented in 1803 by John Dalton

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.
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.
What solid can you use to make a paper mache model of the globe?
Sphere

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.
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.
