QUESTION 8 5 points Save Answer Which of the following statements is incorrect? The Pauli exclusion principle states that each electron in an atom must have its own unique set of quantum numbers. From Heisenberg's principle, we can determine accurately both the position and velocity of an atomic particle. deBroglie postulated that a beam of electrons should exhibit wavelike properties. Bohr set down two postulates. One describes the energy levels of an electron and the other describes the energy of...

The particle-on-a-ring is a useful model for the motion of electrons around a conjugated macrocycle such as octatetrene, for example. Treat the molecule as a circular ring of radius 0.480 nm, with 10 electrons in the conjugated system moving along the perimeter of the ring. Assume based on the Pauli Exclusion Principle that in the ground state of the molecule each state is occupied by two electrons with opposite spins. (a) Calculate the energy of an electron in the highest...

Quantum Numbers Score: 4/14 217 answered Question 2 Which of the following correctly summarizes the Pauli Exclusionary Principle? Matter can neither be created nor destroyed. It only changes form during chemical reactions. Electrons orbiting an atom fill the lowest available energy levels prior to filling higher energy orbitals. It is fundamentally impossible to know both the location and velocity of an electron at the same time. The ground state or lowest energy state of an atom is the one that...
