A line emission spectrum (what we saw with the Spectroscope demo and in the POGIL) is produced when an electrons move from one energy level...
to a higher energy level.
into the nucleus.
to a lower energy level.
to another position in the same sublevel.
Excited atoms emit (release) light when their electrons...
move to higher energy levels
stay in the energy level they are in
return to lower energy levels
are shifted from p to d sublevels
The line emission spectrum of an element...
is the same for every element in the same row on the periodic table.
is the same for every element in the same column on the periodic table.
is different every time you test the same element.
is different from any other element.
If electromagnetic radiation A has a lower (smaller) frequency than electromagnetic radiation B, then how does the wavelength of A compare to B?
They will have the same wavelength.
Radiation A will have a larger (longer) wavelength.
Radiation B will have a larger (longer) wavelength.
As the wavelength of EM radiation decreases, its energy will...
increase
decrease
stay the same
As the wavelength of EM radiation decreases, its speed will...

RANK the electron transitions below based on how much energy is released during the transition. (1-least energy, 5-most energy) Drag the numbers to the RANK column.
Then, based on how you ranked the energy, match each transition to a color of light that would be released. Drag the colors to the COLOR column.
You can use the electromagnetic spectrum that is projected on the front board to recall which colors have more or less energy.
