He contributed by naming oxygen.He also composed the Law of Conversation of mass
-
Michael Faraday FRS was an English scientist who contributed to the study of electromagnetism and electrochemistry
-
He first published his Law of Definite Proportions (or Law of Constant Composition) in 1794. This law states that a compound is composed of exact proportions of elements by mass regardless of how the compound was created
-
He is best known for proposing the modern atomic theory, and for his research into colour blindness.Proposed that all matter was composed of atoms, indivisible and indestructible building blocks.
-
He discovered the existence of radioactivity. This is a very common treatment for a variety of medical conditions, and it harnesses the power of radioactivity.
-
Thomson identified the negatively charged electron . Deduced that the electron was a component of all matter and calculated the charge to mass ratio for the electron.
-
Pierre and Marie Curie are best known for their pioneering work in the study of radioactivity, which led to their discovery in 1898 of the elements radium and polonium.
-
treated matter and energy as exchangeable. Albert Einstein became famous for the theory of relativity, which laid the basis for the release of atomic energy.
-
proposed the nuclear atom as the result of the gold-foil experiment in .This was a very radical proposal that flew in the face of Newtonian Physics.
-
proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities
-
a German physicist, is best known as the originator of the quantum theory of energy for which he was awarded the Nobel Prize in 1918.
-
an American experimental physicist honored with the Nobel Prize for Physics
-
He discovered the neutrons in atoms . bombarded beryllium atoms with alpha particles. An unknown radiation was produced.
