Generally, the theoretical first is given to Richard Laming of England in 1851.
More theoretical work and the term "electron" came from G. Johnstone Stoney between 1874 and 1891.
The actual "discovery" is given to J. J. Thomson in 1897.
when did thomson say there are small, negatively charged particles inside an atom
Isac Newton I think.
Heisenberg/thomsons
J.J. Thomson
The year was 1897.
Bohr.
Thomson
J.j thomson
Electrons are negatively charged (around the nucleus) and protons are positively charged (inside the nucleus)
There are three main particles in an atom. The electron, which is negatively charged, the proton, which is positively charged, and the neutron, which carries no charge.
no,not at all.When a charged electron came near to sphere,sphere get not charged but polarity came inside it due to mutual induction.
The nucleus can be found in the center of an atom. The electrons can be found in the 'surface' if an atom is considered to be a sphere.
The negatively charged particles that move around the atom's nucleus is called electrons.
The answer is electrons.
When an atom gains an electron the no of negatively charged particles increases inside the atom and the atom gets negatively charged.

They are negatively charged particles. electrons are found inside an atom, outside its nucleus.
negatively charged
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
action potential
I do, along with all scientists and educated people in the world know that an atom of matter contains tiny negatively charged particles. They are called 'Electrons'. In antimatter, the proton equivalent carries a negative charge.
Electrons are negatively charged (around the nucleus) and protons are positively charged (inside the nucleus)
in an atom there are mainly 3 particles namely neutrons which are neutral,protons which are postively charged,electrons which are negatively charged .Neutrons and protons are present inside the nucleuswhereas electrons are present outside it and are free to move.Only electrons take part in chemical reactions.
