In the previous Chapter, we learnt about how atoms are indivisible. We said that different substances are combinations of different atoms. But, how are these atoms different?

We said that atoms are like letters of the alphabet. Taking different combinations of the letters, we can form billions of words. Similarly, taking different combinations of the atoms, we get different substances.
Assume that there are only 10 different atoms. How many different substances can you form with these 10 atoms?
  • \(1\)
  • \(10\)
  • \(20\)
  • As many as we want
