What feeling led Thomson to infer that partcles that are smaller than atoms do exist?
Well if there is more negative charge than .......................
What else can I help you with?
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
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.
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.
Who discover atoms contains electrons?
j.j Thomson in 1897 found electron
What Thomson called corpuscles are now called what?
What Thomson called corpuscles are now referred to as electrons.
Who first suggests that atoms are made up of smaller particles?
j.j thomson
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Who first determined that atoms contained even smaller particles?
Thomson, which is considered as the discoverer of electrons.
What findings led JJ Thomson to infer that particles are smaller than atoms do exist?
Particles are smaller
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.
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.
How did Thomson's experiment change Dalton's atomic model?
Thomson's experiment provided evidence for the existence of electrons within atoms, leading to the modification of Dalton's model to include subatomic particles. Instead of envisioning atoms as indivisible spheres, Thomson's discovery suggested that atoms were composed of smaller, negatively charged particles (electrons) embedded within a positively charged sphere.
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.
Thomson discovered that atoms were not simple spheres but contained what?
Thomson discovered that atoms were not simple spheres but contained smaller negatively charged particles called electrons, embedded within a positively charged material. This discovery formed the basis of the plum pudding model of the atom.
What discovery lead j.j Thomson to decide that atoms were not indevisble but are actually composed of smaller parts?
J.J. Thomson discovered the electron through his experiments with cathode rays, which led him to propose the "plum pudding" model of the atom - where negatively charged electrons are embedded in a positively charged "pudding." This discovery challenged the idea that atoms were indivisible, suggesting they were composed of smaller parts.
What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Which of Dalton's statements about the atom was proven false by j.j Thompson?
One of Dalton's statements that was proven false by J.J. Thomson was the idea that atoms are indivisible and cannot be further divided. Thomson's discovery of the electron showed that atoms are made up of smaller particles, leading to the development of the plum pudding model of the atom.
