John Dalton was born September 6 1766 and died July 27 1844. He is best known for his work in development in the modern atomic theory and research into color blindness. He did most of his research during 1794 until he died.
John Dalton’s atomic theory was that atoms are indivisible and also indestructible. All matter is made of atoms. Compounds are formed by multiple of different kinds of atoms.
John Dalton,s most notable experiment was Extraordinary Facts to the Vision of Colors. This was the most notable because it was the first paper ever on color blindness. He realized this condition was hereditary because him and other family members had it.

Thomson’s atomic theory is that electrons can move through anything. He first discovered this is when he was testing if electrons could move through a tube the electrons ended up making it through. That gave him proof he need to have an answer for him self.
Ernest Rutherford was born on August 30 1871 and died October 19 1937. He studied physics and was very good at it. He also enjoyed them. He did most of his studying at the university of Canterbury Collage.
Ernest Rutherford’s most famous science experiment is when he found a much simpler way to identify radio waves. He figured this out by doing many different types of test. These test consisted of him doing multiple different trails and recording his data. After he figured all of this out he shared it to everyone. This made him more known.
Ernest Rutherford’s atomic theory is that the the atom is real. He got this with the help of two partners Hans Geiger and Ernest Marsden. The three of them found the existence of an atom is real.
