With the help of activity in daily life, how can you prove that atoms are divisible?

 Activity:

Take a scale, rub it on hair, try to attract a small bit of paper.

Now divide the bit of paper further into smaller pieces.

Again bring the charged scale near to these pieces of paper.

You will observe that the bits of paper still get attracted

Conclusion:

This activity shows that the atom contains charges and these charges are opposite in nature which shows the attraction. Hence here scale and paper are oppositely charged and hence attract each other. Also, every atom has at least one sub-atomic particle.
