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 the electron and how?
J.J. Thomson discovered the electron in 1897 through his experiments with cathode rays. He observed that these rays were made up of particles much smaller than the atom, leading to the identification of the electron as a fundamental constituent of all matter.

a cathode ray
What particles did jj Thomson discover?
J.J. Thomson discovered the electron in 1897 while conducting experiments with cathode rays. This discovery was groundbreaking as it provided evidence for the existence of subatomic particles.
What is the contribution of j j Thomson to the development of the periodic table?
JJ Thomson discovered the electron in 1897.
Who found the electron?
The electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's discovery of the electron revolutionized the field of physics and laid the foundation for modern atomic theory.
When did JJ Thomson discover the electron?
J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.
What observations did Thomson make to suggest that an electron has negative electric charge?
Thomson observed that a cathode ray bent when in the presence of a magnetic field. After the cathode ray bent the opposite way when the opposite pole of the magnet was placed next to it, Thomson concluded that the cathode ray had a negative charge.
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 E-word was the first elementary particle to be discovered?
The electron was the first elementary particle to be discovered in 1897 by J.J. Thomson. It is a fundamental constituent of matter and carries a negative electric charge.
What electric charges did the beam Thomson used have?
The beam J.J. Thomson used in his cathode ray tube experiments had a negative electric charge. This was confirmed by observing the deflection of the beam in the presence of electric and magnetic fields.
Who described the Atom As negative charges scattered through a ball of positive Charles?
JJ Thomson, who discovered the electron.
Who discovered the electron How?
The electron is a fundamental subatomic particle that was identified and assigned the negative charge in 1897 by Sir John Joseph Thomson and his team of British physicists.

What did Thomson prove?
J. Thomson discovered the electron.
What experimented J.J. Thompson do?
J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.
