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.
In his proposed model of the atom J.J. Thomson imagined the atom contained .?
Thomson is responsible for discovering that an atom contains electrons.
Which model of the atom illustrated that an atom was a cloud of an positive charge with electrons randomly embedded within it?
The plum pudding model by JJ Thomson.
Thomson's experiments were significant in that they questioned?
whether matter is made up of atoms. whether the atom has a positive or negative charge. whether atoms will form compounds with other atoms. whether the atom could be broken up into smaller units.
Who provided the evidence that atom contains subatomic particle?
It was J. J. Thomson (Joseph John Thomson)

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.
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.
Who provided evidence for the nucleus in an atom?
Ernest Rutherford
