$\huge{\underline{\underline{\mathfrak{Answer}}}}$

An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels

Answer 2

Electron

it is negative charge partical

1e is equal to 1.602*10^-19 charge

When electron drifted in potential it means there is potential in conductor and current is flow in conductor positive to negative opposite of electron (negative to positive ).

Sir j.j Thomson discovered electron .
