Describe the following structures of a wave:
Wavelength, crest, trough, amplitude.
Wavelength: The distance from one crest to another crest
Crest: The top of a wave
Trough: The bottom of a wave
Amplitude: The distance from the crest to the baseline
How many electrons are in the 3p sublevel?
6
In an electron cloud, what does a denser region indicate?
A greater chance of finding an electron in that area.
What is the orbital notation for carbon?
(1s2 , 2s2 , 2p2) [using orbitals]
When an electron falls from a higher energy level to a lower energy level, what happens?
Energy is released in the form of light, called a photon.

List the following parts of an atom from largest to smallest:
Electron, Atom, Sub-level, Orbital, Energy Level.
Atom, Energy level, Sub-level, Orbital, Electron.
Why are spectral lines often compared to fingerprints?
Every chemical element has a completely unique pattern of light emission or absorption.
What does the number, letter, and exponent mean?
The number is the energy level
The letter is the sublevel
and the exponent is the # of electrons in the sublevel
What is the lowest-energy arrangement of electrons in an atom called?
Ground state
Describe the relationship between wavelength and:
velocity, frequency, and energy.
The shorter the wave, the greater the frequency.
The longer the wave, the greater the velocity.
The shorter the wave, the greater the energy.
How many electrons can be found in the 1st energy level?
2 electrons
The relationship between wavelength and frequency can be described as:
inverse
What is the short hand configuration for Tungsten?
[Xe] 6s24f145d4
Describe the process of which a photon is released in your own words. (must use the terms:
Electron, Photon, Energy level, Ground state, Excited state,
An atom gains energy in the form of electric current or heat, a valence electron goes from ground state and jumps up an energy level to an excited state. When the electron goes back down to ground state, the energy is released in the form of a photon.
A wave is measured to have an energy of 1.67 x 10-20 Joules. What is the wavelength of this wave?
E = hv h = 6.626e-34
c = 𝛌v c = 3.00e8
0.0000119 nm or 1.19 x 10-5 nm
How many electrons can be found in the 4th energy level?
32 electrons. (2n2) (2 x 42)
The color of light emitted by an atom depends on...
The amount of energy released
