  • John Dalton named these smallest particles "atoms," which means 'indivisible'.
  • Pakudha Katyayama, another Indian philosopher, proposed that these particles normally exist in a combined form, giving rise to various forms of matter.
  • The laws of chemical combination are fundamental principles that interacting atoms and molecules adhere to.
