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.
J.J. Thomson discovered the existence of small negatively charged particles, later named electrons, inside an atom through his cathode ray tube experiments in 1897. This discovery laid the foundation for the development of the atomic model.
Electrons are negatively charged (around the nucleus) and protons are positively charged (inside the nucleus)
Inside a magnesium atom, you will find a nucleus made up of 12 positively charged protons and usually 12 neutral neutrons. Surrounding the nucleus are 12 negatively charged electrons distributed in energy levels or shells.
When an object gains or loses electrons, it becomes negatively or positively charged. In this case, if electrons were transferred to the sphere, making it negatively charged, then the positive charge in the sphere neutralizes the negative charge of the electrons, resulting in an overall neutral state for the system.
The electromagnetic force is the most important force inside an atom. It is responsible for holding the negatively charged electrons in orbit around the positively charged nucleus.
The answer is electrons.
The negatively charged particles that move around the atom's nucleus is called electrons.
When an atom gains an electron the no of negatively charged particles increases inside the atom and the atom gets negatively charged.

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.
They are negatively charged particles. electrons are found inside an atom, outside its nucleus.
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)
The inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.
