Why was Dalton's model of the atom changed after Thomson's experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
Red spheres represent oxygen atoms and green spheres represent chlorine atoms. Write a balanced chemical equation for the reaction?
This is the picture.
What did John Dalton publish?
John Dalton published his atomic theory in 1808, proposing that all matter is made up of small, indivisible particles called atoms. He also introduced the concept of atomic weight and the idea that elements are made up of atoms of a single, unique type.
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
What theory describes the way atoms are arranged within a molecule?
The theory that describes the way atoms are arranged within a molecule is called valence bond theory. This theory explains how covalent bonds are formed by the sharing of electron pairs between atoms and how the arrangement of atoms in a molecule is determined by the overlap of atomic orbitals.
What scientist said atoms are spheres?
James Clerk Maxwell, a Scottish physicist, suggested that atoms were tiny spheres in the 19th century. His work built on the atomic theory proposed by John Dalton.
Who described atoms as small spheres that could not be divided into anything smaller?
John Dalton (he mentioned about this in his atomic theory).
Who compared atoms to marbles?
The physicist John Dalton is credited with comparing atoms to marbles in his atomic theory proposed in the early 19th century. Dalton's theory suggested that each element is made up of its own unique type of atom, much like how marbles of different colors and sizes represent different elements.
What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
Why was Dalton's model of the atom changed after Thomson's experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
Did john Dalton work with neutrons?
No. He did contribute to atomic theory, but the concepts he published dealt solely with the atoms themselves and not with subatomic particles.

Who discovered all things are made of atoms?
In my textbook it sayes that actually Dalton believed that all substances are made of atoms, and this was part of his atomic theory, which he published in 1803.
How did john dalton ivent atomic theory?
He simply proposed that the 'indivisible' parts of masses, known as atoms, were tiny spheres. He did no experiments to test this, but future physicists would begin to show interest in this theory and begin to evolve it further. Now, our current theory is that atoms are composed of a nucleus(where there are protons and neutrons), and energy shells(where electrons orbit the nucleus at incredibly high speeds).
