-
He tried to turned other substantive such as lead to gold. Ideas led to combining elements.
-
Came to the conclusion that everything was made up of tiny indestructible particles that he named "atoms".
-
He identified the known elements fire, water, earth, air, and cosmos. He also laid down the fundamentals of philosophy, and developed the Platonic Theory.
-
He disproved the "four element theory", and helped define the definition of element. Robert also discovered atomic compounds are combinations of elements, and that elements cannot be broken down any further.
-
He found out that mass never changes, and also helped construct the metric system. He's also known as the father of chemistry, and Antoine discovered the role of oxygen in combustion.
-
Dalton's Law, and first scientist who studied atoms on mass and weight. Theory that all matter is made of atoms, the figured out atoms couldn't be created or destroyed.
-
He discovered the periodic law 1969. Physical and chemical properties were related to atomic mass. Elements with similar properties fell under the same vertical in the periodic table.
-
Discovered radioactivity in 1898 and she figured out that it's lethal, because she also died from it. She figured out that elements lose electrons over time.
-
Used diffusion to determine the size of molecules and atoms. He invented the equation e=mcsq. He also had the theory of relatively.
-
Discovered the nucleus and completed the Gold Foil Experiment.
-
He used cathode rays to map electrons, and was one of the contributors to the Spectrograph
-
He discovered atom in 1913 and Noble Prize in 1922. Niehls found out that Electrons on the outer orbit determine the properties of the atom. Electrons have separate orbits.
-
He made the atomic battery, and X-ray's. He used X-Ray's to correct elements positioning on the Periodic Table.
