What is on this test? 
c = wavelenth x f calculations E = h x f calculations Knowing the relationships between f, wavelength and energy (what goes up or down) Knowing the comparative f and wavelengths of all the types of waves.) Which waves carry more or less energy than other waves. Being able to select the correct electron configurations for ANY element. Being able to pick the correct orbital notation for ANY element. Explaining how light is created according to the line emission spectrum. 

The product of the frequency and the wavelength of a wave equals the... 
speed of the wave. 

If electromagnetic radiation A has a lower frequency than electromagnetic radiation B; then compared to B the wavelength of A is. 
longer 

The energy of a photon or quantum is related to its 
frequency

in specific allowed orbits. 

The lowest energy state of an atom is called its _______. 
ground state 

If the frequency of light is 2.5 x 10^14 Hz what is the wavelength of the light? 
1.2 x 106 m
wavelength = c/f 

What is the frequency a light source emitting with a wavelength of 2.0 x 10^8 m? 
1.5 x 10^16 Hz

What rule or principle states that electrons will occupy the lowestenergy orbital that can receive it? 
Aufbau Principle 

What rule or principle states that orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron? 
Hund's Rule


What type or relationship exists between wavelength and frequency: direct or inverse? 
inverse, because when one goes up the other must decrease OR if one decreases the other must increase.

What is the formula for speed of light; c=???? 
c = f x wavelength 

If electromagnetic radiation A has a higher frequency than electromagnetic radiation B; then compared to B the wavelength of A is 
shorter 

Is the energy of a photon directly or inversely related to the frequency of the photon. 
Energy and frequency of a photon have a DIRECT relationship...if one goes up, the other goes up. 

The lineemission spectrum is (the same OR unique) for various light sources. 
it is different (unique) for each light source (we observed this in the lab. 

When did Bohr hypothesize a photon is light is released:
A) when an electron went from the ground state to the excited state
or

Write the correct noble gas configuration for Br. 


What is wrong with the electron configuration pictured?

The 3p orbital should fill with 6 electrons before beginning to fill the 4s orbital. 

What is wrong with the electron configuration pictured? 
Both electrons in the 3s orbital should have opposite spins (one up and one down).
