Electromagnetic Spectrum
What colors are present in the visible spectrum
What are the colors of the rainbow
What is the equation proposed by Max Planck called?
What is orbited the nucleus like a solar system
Atoms are always vibrating, moving, rotating, and tumbling over each other. When they do this they are exhibiting what kind of energy?
What is inversely proportional. When wavelength increases, frequency decreases. When wavelength decreases, frequency increases.
What color in the visible spectrum has the longest wavelength?
What is red
What is Plancks relation equation?
What is E=hf
As you move away from the nucleus, the energy level for the electrons
What is increases
To move into an excited state, atoms must
What is absorb energy by a photon
You measure a wavelength by
Measuring peak to peak
What are Radio waves and gamma rays respectively
How are energy and frequency related?
What is directly proportional. Energy increases as frequency increases and vice versa.
How many electrons are permitted in the first energy shell? n=1
What is 2 electrons
When all an atom's electrons are in their lowest-energy orbitals it is in its
What is ground state
The spectrum of wavelengths emitted by each element is unique, which means that light spectra can be used to identify the element's presence in a gas or solution. The science of such identifications is called
What is Spectroscopy
What are the particles of light called and what is the energy within those particles called?
What are photons and quanta of energy
We can manipulate Plancks relation and insert this velocity to help solve for frequency. What is that velocity?
What is the speed of light
According to the Bohr model, how many electrons are permitted in n=2 and n=3?
What is 8 electrons
When an electron is excited and needs to come back down from its excited state it
what is emits a photon in the form of light/color/wavelength.
When an electron moves from n=2 to n=4, what happened?
What is the contemporary theory of light?
What is the idea that light exhibits both wave-like properties and particle-like properties
We can manipulate the velocity equation to solve for frequency. When we do this we insert that new equation into plancks relation to get a new equation. What is it?
E= hv/ lambda
The two issues with the bohr model were
what are there was no explanation as to why electrons stayed in their orbit, and for atoms other than hydrogen the energies between levels don't match up perfectly to observed wavelengths
How many different frequencies can be emitted by the hydrogen atom?
four
What does the Rydberg formula predict?
What is the wavelengths that are emitted from a hydrogen atom
