In his experiment, he attempted to put something through the atom
Directed a narrow beam of alpha particles at a thin piece of gold foil
98% pf the particles went through the foil while about 2% of them were deflected at large angles and 0.01% of the alpha particles bounced off the gold foil
Concluded that Thomson's plum-pudding was incorrect because the alpha particles did not travel straight through the foil, as preddicted by Thomson's model
Altered Rutherfrod's model so as to incorporate the atom's energy changes as it emits and absorbs light
Each electron orbit has a fixed energy level and the quantum describes the amount of energy needed for An electron to move from one energy level to another
The further the electron is from the nucleus, then the more energy it has
Each orbit has a certain energy level; the energy of each orbit is characterized by a specific number
An atom is excited when an electron leaps from a lower energy state to a high one and it is in a ground state when it returns from a higher level to a level closer to the nucleus
