Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
Which of the following is true about the nucleus of an atom?
J.J. Thomson's experiments provided evidence that an atom contains negatively charged particles.
What Evidence did JJ Thompson use to develop his model?
J.J. Thomson used experiments with cathode rays to discover the electron. By observing the way these rays moved in an electric field, Thomson determined that they were negatively charged particles much smaller than the atom. This led him to propose the "plum pudding" model of the atom, where electrons were embedded in a positively charged sphere.
In his proposed model of the atom J.J. Thomson imagined the atom contained .?
Thomson is responsible for discovering that an atom contains electrons.
Did JJ Thomson experiments that showed that atoms cannot be divided into smaller particles?
Yes, J.J. Thomson's experiments using cathode rays led to the discovery of the electron and the plum pudding model of the atom. This model suggested that atoms are not indivisible, but composed of smaller particles.
What did J. J. Thomsons experiments provided evidence about an atom?
J. J. Thomson's experiments provided evidence for the existence of electrons as subatomic particles within the atom. This led to the plum pudding model of the atom, where electrons were embedded in a positively charged "pudding." These experiments laid the foundation for our understanding of atomic structure.
What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.
Who provided the evidence that atom contains subatomic particle?
It was J. J. Thomson (Joseph John Thomson)

What evidence supported Thomson's hypothesis that negative particles he observed came from inside atoms.?

What was the name of the concept model that Thomson proposed based on his experiments?
JJ Thomson called his model of the atom the plum pudding model.
When did JJ Thomson do stuff about the atom?
Thomson did much of his most important work in the late 1800's. His famous cathode ray experiments where conducted in 1897.
Which of the following is true about the nucleus of an atom?
J.J. Thomson's experiments provided evidence that an atom contains negatively charged particles.
How did the discovery of electrons shows that there are also positively charged parts of the atom?
The discovery of electrons by J.J. Thomson provided evidence for the existence of positively charged particles in the atom because atoms were found to be electrically neutral overall. Thomson's experiments with cathode rays showed that electrons carried a negative charge, leading to the conclusion that there must be positively charged particles in the atom to balance the negative charge of the electrons.
What evidence convinced J.J Thomson that an atom consist of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
What Evidence did JJ Thompson use to develop his model?
J.J. Thomson used experiments with cathode rays to discover the electron. By observing the way these rays moved in an electric field, Thomson determined that they were negatively charged particles much smaller than the atom.
