question 2 (6 points)
match each item with the correct statement below.
column a
1 discrete bundle of electromagnetic energy
2 energy needed to move an electron from one energy level to another
3 number of wave cycles passing a point per unit of time
4 distance between wave crests
5 separation of light into different wavelengths
6 frequencies of light emitted by an element
column b
a. atomic emission spectrum
b. frequency
c. spectrum
d. wavelength
e. quantum
f. photon

Explanation:

• For 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.
• The aufbau principle states the tendency of electrons to enter orbitals of lowest energy first.
• Electron configuration is the arrangement of electrons around the atomic nucleus.
• The Pauli exclusion principle says each orbital has at most two electrons.
• For Question 2:
• A photon is a discrete bundle of electromagnetic energy.
• The energy needed to move an electron from one energy level to another is related to quantum concepts.
• 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 a spectrum.
• The frequencies of light emitted by an element is the atomic emission spectrum.
