The electron was discovered by?
Niels Borh, a Danish scientist, discovered this in 1913
What did Thomson's cathode-ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists learn about electrodes and that atoms were comprised of many small particles, which they did not know existed. They also learned from this tube that all the electrons were the same regardless of what elements they came from.
What did William Crookes discover with his glass tube experiment?
Cathodes(electrons) (-)
Can you briefly explain Torricelli's Experiment between mercury and atmospheric pressure?
Torricelli's experiment: Spring 1644, Florence (Italy): Venue of a famous experiment: Torricelli did his experiment with quicksilver or mercury. He proved two things with this experiment: 1, Nature doesn't abhor the void (nature doesn't fear vacuum) 2, and that the air has weight: He used a glass barometric tube of about 1 m in length which was open at one end and closed at the other end. He also used a glass funnel, which was used to pour in mercury. He put the glass funnel inside the one end open glass barometric tube of 1m and poured mercury into it. He used this method to avoid the formation of any air bubbles inside or in other words, it was not to create any void inside the tube. He removed the glass funnel after pouring the mercury, and then closed one end of the barometric tube with his finger, inverted it to make the open end at the bottom and the tube was inserted into a vessel containing mercury carefully without forming any air bubbles. He found that the mercury in the 100cm tube dropped to 76cm. He did the same experiment with water. But that required a long tube. Water has a density 136 times less than that of mercury, and this experiment returned the water column at a height of 103m. This means that the height of the water column = the height of the mercury column (76cm) X relative density of water with respect to mercury (136).
What did john Thomson use to deflect the cathode rays?
he dint did nething to deflect them thet went straight to the anode +ve of the tube becoz opposite attracts.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
What piece of equipment did JJ Thomson use in his atomic theory experiment?
JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.
In the Thomson experiment to determine the Specific charge of an electron If the pressure in the discharge tube is made is made as low as nearly zero dose conduction takes place?
If the pressure in the discharge tube is nearly zero, there are very few gas particles present to ionize and create a conductive path for the electrons. This lack of gas particles results in very low conductivity and can prevent conduction from taking place in the Thomson experiment to determine the specific charge of an electron.
What famous experiment did J.J thomas conduct?
J.J. Thomson is famous for his experiments that led to the discovery of the electron in 1897, which revolutionized our understanding of atomic structure. His work with cathode rays in a vacuum tube allowed him to determine the charge-to-mass ratio of the electron.
What was the name of jj equipment (experiment) he did?
it was electrons
Which scientist is credited with discovering the electron?
J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative
What experiment do Thomson do?
He hit plates with light
What was John Thomson's experiment for the modern model?
John Thomson's experiment involved studying the properties of cathode rays in a cathode ray tube. By observing the behavior of these rays in the presence of electric and magnetic fields, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment provided important evidence for the existence of subatomic particles and laid the groundwork for the development of the modern atomic model.
Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
What did thomson's cathode-ray tube experiment help scientists learn?
Thomson's cathode-ray tube experiment helped scientists understand that electrons are negatively charged particles within atoms. This experiment contributed to the development of the plum pudding model of the atom, which proposed that electrons are embedded in a positively charged sphere within the atom.
What was Thomson's cathode ray tube experiment?
Thomson's cathode ray tube experiment in 1897 involved passing electric current through a sealed glass tube containing a low-pressure gas. He discovered that the rays produced in the tube, later termed electrons, were deflected by electric and magnetic fields, leading to the conclusion that they were negatively charged particles. This experiment provided evidence for the existence of subatomic particles and helped pave the way for the development of the atomic theory.
The electron was discovered by?
Niels Borh, a Danish scientist, discovered this in 1913
