British chemist Robert Boyle- he thought that all matter was made of very tiny particles called corpuscles.
Dutch microscopist, Antoni van Leeuwenhoek (1632-1723), described the size and shape of "red corpuscles" and rendered the first illustration of them in 1695.
J.J Thomson :)
J.J. Thomson discovered the negatively charged particles, electrons in 1897.

An electron is negatively charged.
Negatively charged particles in an atom are known as 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.
J.J. Thompson discovered the existence of negatively charged, sub-atomic particles, all with the same charge to mass ratio. He called them "corpuscles."

An electron is negatively charged.
Electrons are the negatively charged particles in atoms. This is not an entertainment and arts question.
Electrons are the negatively charged particles to which the flow of electricity is attributed.
The negatively charged particles of an atom are in an outer shell.
Electrons are the negatively charged particles to which the flow of electricity is attributed.
Negatively charged particles are called electronsI'M SURE BELIEVE ME !!!!electrons are charged -1 and protons are charged +1.
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
