When we first learn to write electron configurations for atoms, we use the Pauli Exclusion
Principle (PEP) and Hund's Rules to ensure that what we write is consistent with what we
observe in nature, the Periodic Table. Consider carbon and oxygen and write the correct ground
state electron configurations for both; having done so, reflect on how you intuitively used the
PEP and Hund's Rules. Now think about the formal statement of the PEP written as Postulate 6
of Quantum Mechanics.
All electronic wave functions must be antisymmetric under the interchange of
any two electrons.
Now we come to it; determine the most stable atomic term symbol for both elements and
explain Hund's Rules (see below) are manifested in the singular that you used to write
the correct ground state electron configurations.
Hund's Rules
1. The state with the largest value of S is the most stable, and stability
decreases with decreasing S.
2. For states with the same value of S, the state with the largest value of L…
When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. What is the longest wavelength of electromagnetic radiation capable of ionizing this hydrogen atom in an excited state? Report your answer in nanometers.
Which of the following statements about an electron is TRUE according to the quantum mechanical model of the atom?
The shape of an orbital is determined mathematically from the wavefunction of an electron
The position and velocity of an electron can simultaneously be determined very accurately
A single electron can interfere with itself
