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...

Question 1 (2 points) Which of the following statements is true? It is possible to simultaneously observe both the wave-like and particle-like properties of an electron in a single experiment. An orbital is the path followed by an electron as it moves about an atom. The principal quantum number (n) describes the energy of an orbital. Bohr's model confirmed the existence of orbitals.

An orbital-filling diagram shows the number of electrons m each orbital, which are shown in order of energy. The placement of electrons in orbitals follows a certain set of rules. Lower energy subshells fill before higher energy subshells. The order of filling is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. The periodic table can be used to help you remember this order. An orbital can hold up to...
