True or False.
(a) According to the Heisenberg Uncertainty Principle, it is
impossible to know simultaneously both the exact
momentum of the electron and its exact location in space.
Answer: ____________
(b) According to Born, taking the square root of ψ would give the
probability of finding the electron in a certain
region of space at a given time.
Answer: ____________

assumed that energy can only be emitted in
discrete amounts.
Answer: ____________

higher energy state to the lower energy state,
electromagnetic radiation is released.
Answer: ____________
