What is the definition of a continuous line spectrum?
It contains all wavelengths of light in a certain range. It does not have any gaps
What is the definition of a line spectrum?
It is a spectrum only showing certain frequencies at specific wavelengths
Draw the line emission spectra of hydrogen.
What is the definition of convergence?
When the set of lines is converging towards the higher energy end, so the electron is reaching a maximum amount of energy. The maximum corresponds to the ionisation energy of the electron
Where do the electrons jump to from higher levels in the hydrogen emission spectrum?
From higher levels down to n=2 energy level
What energy level do electrons jump to for infrared?
n = infinity to n=3
What energy level do electrons jump to for visible light?
n = infinity to n=2
What energy level do electrons jump to for ultraviolet?
n=infinity to n=1
How many electrons can s shell contain?
2 electrons
How many electrons can p shell contain?
6 electrons
How many electrons can d shell contain?
10 electrons
How many electrons can f shell contain?
14 electrons
