How did Thomson know that the electrons that he had discovered had a negative charge?
He devised a crook's tube with a near perfect vaccum with two aluminum plates in the center of the tube. One plate served as the anode to a circuit while the other served as a cathode, effectively creating a magnetic field between then with a negative field on one side and a positve field on the other. electrons (cathode rays) were then passed through, Because electrons are negatively charged, the negatively charged anode will repel them and force them to strike the florescent screen at a lower spot than if allowed to pass through freely. When the current it reversed the electrons strike the screen at a higher point than would normally occur

Who identified electrons to have a negative charge?
J.J. Thomson is credited with identifying electrons to have a negative charge through his experiments with cathode rays in the late 19th century.
What did Thomson call electrons?
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
How is negative charge distributed in the atom according to Thomson's model?
Just as seeds in a watermelon electrons are embedded in a positive ball
What particles will have a negative charge?
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
How j.j Thomson discovered electrons are negative?
J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.
What was the scientist name who discovered the electrons charge?
The scientist who discovered the charge of electrons was J.J. Thomson. He determined the charge-to-mass ratio of electrons through his experiments with cathode rays in the late 19th century.
Who identified electrons to have a negative charge?
J.J. Thomson is credited with identifying electrons to have a negative charge through his experiments with cathode rays in the late 19th century.
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
In Thomson's plum pudding model what do the plums represent?
The plums represent the electrons, which has a negative charge.
What did Thomson call electrons?
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
What charge is electrons?
Electrons charge is a negative
How did Thomson demonstrate the existence ofthe electron?
Thomson discovered electrons studying cathode rays and estimating the mass and electrical charge of the component particles.
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
Who discovered that atoms have negative electric charge?
There were several scientists that discovered that atoms contained electric charges. One of the first to look at their charges more closely was J.J. Thomson.
What particle did J. J. Thomson discover?
according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
