Who find electron?
The electron was first discovered by J.J. Thomson in 1897 through experiments with cathode rays. He observed that these rays were made up of negatively charged particles, which he called electrons.
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
Who first postulated the existence of the electron?
J.J. Thomson first postulated the existence of the electron in 1897 through his experiments with cathode rays. He proposed that cathode rays were composed of negatively charged particles, which he called "corpuscles" and later became known as electrons.
Which describes electron probe microanalysis to determine the elemental composition of glass?
Electron probe microanalysis is a technique that bombards a sample with an electron beam, exciting the electrons in the atoms of the sample to emit characteristic X-rays. By detecting and measuring these X-rays, the elemental composition of the glass can be determined. This method is commonly used in materials science to analyze the elemental composition of various samples.
Who proved the existence of the electron?
Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. But many scientists contributed to the discovery of the electron.
How does electron capture generate X-rays?
The capture creates a "hole", or missing electron, that is filled by a higher energy electron that emits X-rays.
What is modern name for cathode rays?
A modern day name for cathode rays is an electrons.
If the gamma rays and X-rays have the same frequency what will the electron have?
If the gamma rays and X-rays have the same frequency, the electron will have the same energy regardless of which type of radiation is interacting with it. The energy of the electron is determined by the frequency of the radiation it absorbs, not the type of radiation.
What is the modern day name for cathode rays?
Cathode rays are electron beams.
What did experiments with cathode rays lead to the discovery of what?
experiments with cathode rays lead to the discovery of the Electron.
What type of x rays produce beta rays?
X-rays are not capable of producing beta rays. Beta rays are a form of ionizing radiation emitted by certain types of radioactive nuclei. X-rays are electromagnetic radiation produced through processes like electron transitions in atoms or by high-energy electron collisions.
What does electron beam therapy use?
Electron beam therapy uses high-energy electron beams to deliver radiation treatment to cancerous tumors. By targeting the tumor site with precise radiation doses, electron beam therapy can help destroy cancer cells while minimizing damage to surrounding healthy tissue.
What are cathode rays also known as?
Electron beam or e-beam
Are Betta rays radioactive?
No. Neither an electron nor an anti-electron will decay by themselves. If a positron (anti-electron) encounters an electron, both will get destroyed, but this is not radioactivity. Radioactivity is normally used for atoms, and refers to the fact that they decay spontaneously.Beta rays, however, are the result of certain types of radioactive decay.No. Neither an electron nor an anti-electron will decay by themselves.

What happens when a positron and a electron collide?
When a positron and an electron collide, they annihilate each other and produce gamma rays. This process is known as electron-positron annihilation. The total energy of the particles is converted into electromagnetic energy in the form of gamma rays.
What particle was observed in the cathode rays?
The negatively charged particle called electron.
