f. wavelength

Explanation:

• Question 1:
• An atomic orbital is defined as a region of high probability of finding an electron.
• The ground state is the lowest energy level of an atom.
• The aufbau principle states that electrons enter orbitals of lowest energy first.
• Electron configuration is the arrangement of electrons around the atomic nucleus.
• The Pauli exclusion principle says that each orbital has at most two electrons.
• Question 2:
• A photon is a discrete bundle of electromagnetic energy.
• A quantum is the energy needed to move an electron from one energy level to another.
• Frequency is the number of wave cycles passing a point per unit of time.
• Wavelength is the distance between wave crests.
• The separation of light into different wavelengths is called a spectrum.
• The frequencies of light emitted by an element is its atomic emission spectrum.
