J.J. Thomson discovered that atoms contain negatively charged particles called corpuscles, now known as electrons, in 1897 through his experiments with cathode rays. This led to the development of the plum pudding model of the atom.
Dutch microscopist, Antoni van Leeuwenhoek (1632-1723), described the size and shape of "red corpuscles" and rendered the first illustration of them in 1695.

What Thomson called corpuscles are now called what?
Thomson's corpuscles are now known as electrons. These are negatively charged subatomic particles found within atoms.
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.
Who discovered small negatively charged particles inside an atom?
J.J Thomson
Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
Which of the following particles is negatively charged?
An electron is negatively charged.
Who is cretited with the electron?
J.J. Thompson discovered the existence of negatively charged, sub-atomic particles, all with the same charge to mass ratio. He called them "corpuscles."
What Thomson called corpuscles are now called what?
Thomson's corpuscles are now known as electrons. These are negatively charged subatomic particles found within atoms.
Who discovered negatively charged particles found outside the nucleus?
Rutherford

Negatively charged particles are called what?
Negatively charged particles are called electronsI'M SURE BELIEVE ME !!!!electrons are charged -1 and protons are charged +1.
Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
Which of the following particles is negatively charged?
An electron is negatively charged.
Negatively charged particles?
Electrons are the negatively charged particles in atoms. This is not an entertainment and arts question.
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.
What negatively charged particles are responsible for the flow of electricity?
Electrons are the negatively charged particles to which the flow of electricity is attributed.
What negatively charged particles are responsible for the flow electricity?
Electrons are the negatively charged particles to which the flow of electricity is attributed.
