-
His hypothesis was that matter is made of indivisible particles caaled atoms. -"father of modern science"
-
His hypothesis was that matter was made of spherical masses in motion.
-
used cathode rays, used with electrons
-
discovered x-rays that use cathode rays that involve atomic theory.
-
described the atom as a ball of positive charge containing a number of electrons
-
Used the "Gold Foil" experiment to determine that the nucleus of the atom is very dense and had a positive charge. Discovered the proton. Electrons were outside the nucleus of the atom.
-
explained the atomic structure of the atom as succesive orbital shells of electrons
model is known as the Bohr plantary model -
identified the electron cloud model as the probable location of moving electrons.
-
figured out you could split the arom.
-
discovered a particle within the nucleus that has a mass similar to that of a proton. thus, he credited with discovering the neutron.
-
atomic bomb which was made from cockroft and waltons discoveries was dropped on Japan to end world war two.
