Here is a list of scientists along with their relevant contributions:

  1. John Dalton - proposed that all matter was made up of atoms.
  2. Marie Curie - helped discover radioactivity.
  3. Ernest Rutherford - came up with a way to determine how radioactive a substance was.
  4. Robert Hooke or Avogadro - came up with a law that focuses on the behavior of molecules. (Note: Robert Hooke is more known for Hooke's Law related to elasticity; Avogadro's principle relates to gas behavior.)
  5. Dmitri Mendeleev - was the first to organize a periodic table of elements.
  6. Boyle & Charles - was one of the first to discover and name gas laws. (Boyle is known for Boyle's law, and Charles for Charles's law, which relates to the behavior of gases.)
