What is the particles in Thomson's tube?
In Thomson's tube, also known as the cathode ray tube, the primary particles involved are electrons. These negatively charged particles are emitted from a cathode and are accelerated towards an anode, creating a stream of electrons, or cathode rays. When subjected to electric or magnetic fields, these electrons can be deflected, allowing for the study of their properties and confirming their charge-to-mass ratio. Thomson's experiments led to the discovery of the electron as a fundamental particle of matter.
What was the result of Thomson experiment?
J.J. Thomson's experiment, conducted in 1897, resulted in the discovery of the electron as a subatomic particle. By using a cathode ray tube, he demonstrated that cathode rays were composed of negatively charged particles, which he called "corpuscles" (later known as electrons). This finding provided evidence for the existence of smaller components of atoms and led to the development of the "plum pudding" model of atomic structure, where electrons are embedded within a positively charged "soup." Thomson's work fundamentally changed the understanding of atomic theory and laid the groundwork for modern physics.
J j Thomsons experements?
In 1897, Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons. (See Figure 1.8 in the textbook for Thomson's experimental setup). From Maxwell's theory, he knew that charged particles could be deflected in a magnetic field
What were the limitations of J.J Thomson atomic model?
J.J. Thomson's atomic model, known as the "plum pudding model," proposed that atoms consist of a positively charged "soup" with negatively charged electrons embedded within. However, it was limited in several ways: it could not explain the results of the Rutherford gold foil experiment, which demonstrated that atoms have a dense, positively charged nucleus. Additionally, Thomson's model failed to account for the discrete energy levels of electrons, as later shown by Bohr's model, and did not adequately explain atomic stability or the behavior of atoms in chemical reactions.
How did Thomson help our understanding of the atom (apex)?
J.J. Thomson contributed significantly to our understanding of the atom through his discovery of the electron in 1897. By conducting experiments with cathode rays, he demonstrated that these rays were composed of negatively charged particles, which he termed "corpuscles," later known as electrons. This finding led to the realization that atoms are not indivisible but consist of smaller subatomic particles. Thomson's work paved the way for the development of the "plum pudding" model of the atom, which described a positively charged sphere with embedded electrons.
Who invented the negatively charged particle electron?
The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.
Who said that there are small negatively charged particle's inside an atom?
not positive but jj thomson
What did John Thompson discover?
J.J Thomson discovered Electrons which is the negatively charged sub-atomic particle of an atom
How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
Is a negatively charged particle the same as a neutral particle?
No, a negatively charged particle (electron) has a negative charge associated with it. A neutral particle (neutron) is neither negatively charged nor positively charged.
What is a negatively charged subatomic particle'?
electronThe electron is a negatively charged particle.
What is a negativly charged particle subatomic particle?
This particle is the electron, negatively charged.
Who discover that What is inside the atom?
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
Are electron negatively charged atoms?
No. An electron is negatively charged but it is not an atom. It is a subatomic particle and the negatively charged component of an atom.
What's negatively charged particle?
A negatively charged partical is an electron.
A negatively charged particle is?
Electron
What is a subatomic particle called that is negatively charged?
This particle is the electron.
