Solution
Electron: An electron is a negatively charged sub-atomic material particle.
- An electron is denoted as e-.
- In cathode ray experiment, rays emitted from the cathode consists of a stream of negatively charged particles called electrons.
- Charge carried by an electron= 1.602 × 10-19 coulomb or 1.602 × 10-19 C.
