Definitions
100
What type of relationship exist between wavelength and frequency?
Inverse relationship. If one goes up, the other must go down. (in terms of multiplication & Division)
100
The dots in the Lewis Dot structure represent what?
The valence Electrons
100
What is ground state configuration for Boron?
1s2 2s2 2p1
100
Copper produced a green flame, while potassium produced a violet flame, which metal had electrons that traveled further from the nucleus?
Potassium's violet flame had more energy.
Due to having more energy, Potassium's electrons could travel further from the nucleus, and as it returned it released the large amount of energy is the form of violet light.
100
the arrangement of electrons in an atom
electron configuration
200
The frequency of a wave is altered from 56.7 Hz to 8.10 Hz. If the original wavelength was 124 nanometers, what will be the new wavelength?
868 nanometers.
Due to the inverse relationship that exist between frequency and wavelength, when frequency is divided by 7, wavelength must be multiplied by 7.

1s2 2s2 2p6 3s2 3p6 4s2 3s10 4p5
200
What type of radiation occurs when an electron produces a wavelength of 3.8 x 10-5?
Infrared
200
the number of waves that pass a given point per second
frequency
300
What is the frequency of a photon with an Energy of 2.4 x 10-20 J?
3.6 x 1013 Hz
Frequency is Energy divided by Planck's constant.
300
What is the dot structure for Chlorine?
300
Draw the orbital notation for Cobalt
300
How many electrons can be held in each sublevel?
S? p? d? f?
S - 2 electrons
P - 6 electrons
D - 10 Electrons
F - 14 electrons
300
a three-dimensional region around the nucleus of an atom that describes an electron’s probable location
atomic orbital
400
What is the wavelength of a wave that has a frequency of 5.812 x 1014 Hz?
What type of wavelength is this?
5.16 x 10-7 m of Green visible light
Speed of light limits you to three sig figs.
10-7 represents visible light, and 5.16 falls between 4.9 & 5.7 thus giving you green visible light.

Give the noble gas notation and dot structure for Bismuth (Bi)
[Xe] 6s2 4f14 5d10 6p3
400
Give the ground state configuration for Yttrium
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d1
400
How many electrons can be held in the third sublevel?
18,
In the third level there are three sublevels, s, p, and d. The s can hold 2 electrons, p can hold 6 electrons, and d can hold 10 electrons for a grand total of 18.
400
the minimum amount of energy that can be gained or lost by an atom
quantum
500
What is the Energy of a wave with a wavelength of 3.21 x 102 meters?
6.19 x 10-28 J
(6.20 x 10-28 J if you round after first step)
First you must solve for V using the wavelength equation which gives you a frequency of 934,579.4393 Hertz (9.35 x 105 Hz). Plug this value into Energy equation.
500
What is the noble Gas notation and dot structure for Berklium (Bk)?
[Rn] 7s2 5f9
Dot structure would have Bk surrounded with two dots that are on different sides of the symbol.
500
Give the ground state for Tungsten (W)
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d4
500
What is the wavelength of a wave that travels from n=5 to n=2? What type of radiation occurs (infared, visible [be specific], or ultraviolet.)
434 nanometers of blue visible light.
Look on the back page of your yellow reference table and use the Bohr Model. 434 nanometers is the same as 4.34 x 10-7 m. This range falls under blue visible light.
500
electrons are emitted from a metal’s surface when light of a certain frequency shines on the surface
