Answer:
From the highest to the lowest
Third excited state (n=4) [tex]\rightarrow[/tex] Second excited state (n=3) [tex]\rightarrow[/tex] First excited state (n=2) [tex]\rightarrow[/tex] Ground state (n=1)
Explanation:
The Bohr Model, by Niels Bohr, is a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun. Niels Bohr in his model states that:
The lowest value of n is 1, which is the ground state
n = principal quantum number
Therefore, from the highest to the lowest, the energy levels are ranked as:
Third excited state (n=4)
Second excited state (n=3)
First excited state (n=2)
Ground state (n=1)
