2. notes
3. starting
4. Atoms
5. Atoms are the building blocks of matter. It is the smallest unit of matter that is composed of three sub-atomic particles: the proton, the neutron and the electron.

9. Cathode ray experiment
10. J. J. Thomson discovered the existence of electrons.
11. He did this using a cathode ray tube, which is a vacuum-sealed tube with a cathode and anode on one end that created a beam of electrons travelling towards the other end of the tube.
12. The air inside the chamber is subjected to high voltage and electricity flows through the air from the negative electrode to the positive electrode.
13. The characteristics of cathode rays (electrons) do not depend upon the material of electrodes and the nature of the gas present in the cathode ray

1. Electrons
2. Electrons are the negatively charged sub-atomic particles of an atom.
3. The mass of an electron is considered to be negligible, and its charge is -1.
4. The symbol for an electron is e–
5. Electrons are extremely positive charges are equal in magnitude. So, the atom as a whole is electrically neutral
6. The first model of an atom to be put forward and taken into consideration.
7. He proposed a model of the atom be similar to that of a Christmas pudding/watermelon
