|
What is monochromatic radiation?
|
Radiation composed of single wavelength
|
|
|
Name the components of the electromagnetic spectrum in order of highest energy to lowest energy?
|
Gamma Rays, Xrays, Ultraviolet, (visible light) Infrared, Microwaves, Radio Waves
|
|
|
What is a Continuous Spectrum
|
a continuous merging of colors
|
|
|
What is Line Spectrum or discontinuous spectra?
|
a view of a spectrum for a particular elements
|
|
|
What was different/important about Bohr's atomic model?
|
*it introduced the idea of quantized energy
*it introduced the idea of electrons absorbing/releasing specific quanta of energy to make changes in energy states |
|
|
Ground State
|
the lowest possible energy state of an atom
|
|
|
Excited State
|
When the electron is in a higher energy state- has excess energy
|
|
|
What do electrons release/gain to jump energy levels?
|
photons
|
|
|
What were some flaws to the Bohr Model?
|
*his model only worked for atoms and ions with only 1 electron
*could not explain the atomic spectra of complex atoms/ions *said that electrons behaved as matter ONLY *said that electrons moved in defined ORBITS |
|
|
What wavelength range does visible light fall in?
|
4 x 10^-7 (violet) to 7 x 10^-7 (red)
|
|
|
In what order (from shortest to longest wavelength) do the 7 different types of electromagnetic radiation come in?
|
Gamma Rays, X Rays, Ultra Violet, Visible Light, Infrared, Microwaves, Radio Waves
|
|
|
Why was Bohr's model important?
|
*Introduced the idea of quantized energy
*idea of electrons absorbing/releasing specific "quanta" of energy to make changes in energy states |
