column a

1. the set of frequencies of the electromagnetic waves

emitted by the atoms of an element

1. the minimum amount of energy that can be lost or

gained by an atom

1. a form of energy that exhibits wavelike behavior as

it travels through space

1. a three - dimensional region around the nucleus of an

atom that describes an electrons probable location

1. the shortest distance between equivalent points on a

continuous wave.

1. the lowest allowable energy state of an atom

use the figure to answer the following questions.

1. which letter(s) represent one wavelength?
2. which letter(s) represent the amplitude?
3. if twice the length of a passes a stationary point every second, what is the frequency of the wave?

Explanation:

• Question 1: The atomic emission spectrum is the set of frequencies of electromagnetic waves emitted by an element's atoms.
• Question 2: A quantum is the minimum energy an atom can lose or gain.
• Question 3: Electromagnetic radiation is energy with wavelike behavior in space.
• Question 4: An atomic orbital is a 3 - D region around a nucleus for an electron's probable location.
• Question 5: Wavelength is the shortest distance between equivalent points on a continuous wave.
• Question 6: The ground state is the lowest allowable energy state of an atom.
• Question 7: Wavelength is the distance between two consecutive identical points (e.g., crest - crest or trough - trough). In the wave diagram, \(A\) and \(C\) represent one wavelength.
• Question 8: Amplitude is the height of the wave from the mid - line (equilibrium position). Here, \(B\) represents the amplitude.
• Question 9: Frequency (\(f\)) is the number of waves passing a point per second. If twice the length of \(A\) (which is one wavelength \(\lambda\)) passes a point per second, then the number of wavelengths per second \(n = 2\). So, the frequency \(f=2\space Hz\).

Answer:

1. d. atomic emission spectrum
2. b. quantum
3. f. electromagnetic radiation
4. c. atomic orbital
5. a. wavelength
6. e. ground state
7. \(A\) and \(C\)
8. \(B\)
9. \(2\space Hz\)
