What is Bohr's first law? | Electrons orbit in circular patterns around a positive nucleus. |
What is Bohr's second law? | Only certain radii are allowed; these must satisfy the requirement that the angular momentum(L) is quantized. |
What is Bohr's third law? | Light is emitted when an electron jumps from a higher energy orbit to a lower energy orbit. |
Since the angular momentum is quantized, then only certain ____________ (radii) are allowed and certain ___________________ are allowed. | orbits, electron energies |
What was Feynman's famous quote? | Atoms are completely impossible from the Newtonian point of view. |
