Electrons & Light
Help!
|
|
||||
|---|---|---|---|---|---|
| wavelength | decreases left to right, distance between 2 crests
🗑
|
||||
| energy | increases left to right
🗑
|
||||
| frequency | increases left to right, the number of waves that pass a particular point in an amount of time
🗑
|
||||
| frequency increases --> | wavelength decreases
🗑
|
||||
| excited electrons | emit light when they fall from higher energy levels to lower energy levels
🗑
|
||||
| ground state | the lowest energy level possible for an electron
🗑
|
||||
| visible light | can be seen by the eye
🗑
|
||||
| shortest wavelength | violet light, x-rays, gamma rays
🗑
|
||||
| longest wavelength | red light, AM radio waves
🗑
|
||||
| wavelength gets shorter--> | frequency gets higher (inverse relationship)
🗑
|
||||
| the speed of light | is the same for all colors of light
🗑
|
||||
| there are many... | different shades of each color
🗑
|
||||
| most energy | violet light
🗑
|
||||
| least energy | red light
🗑
|
||||
| wavelength decreases --> | energy increases (inverse relationship)
🗑
|
||||
| hydrogen emission spectra | 4 colors - red, blue-green, blue-violet, violet, cannot produce more than one color at once since it only has one electron
🗑
|
||||
| boron emission spectra | 5 colors - red, orange, blue-green, 2 blues, 3 violets
🗑
|
||||
| boron has different electrons than hydrogen, so | different shades are created
🗑
|
||||
| smallest wavelength--> | most energy
🗑
|
||||
| spectral lines | are different for each element and identify what the element is, much like fingerprints
🗑
|
||||
| electrons and protons | attract each other
🗑
|
||||
| as an electron gets closer to the nucleus, | the attraction gets stronger
🗑
|
||||
| when an electron moves from an energy level close to the nucleus to one far from it | the electron loses/absorbs energy & light
🗑
|
||||
| when an electron moves from an energy level far from the nucleus to one close to it | the electron gains/releases energy & light
🗑
|
||||
| excited states | higher energy levels
🗑
|
||||
| straight arrow in Bohr model | represents amount of energy put in
🗑
|
||||
| hydrogen electron transition with the UV range (10-400 nm) | 400 is smaller than violet 410 (smallest in hydrogen spectra), so smaller waves need to be produced which involves more energy, n=6-->n=1 (bigger arrow, more energy, shorter wavelength)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
