In the classical view of the atom, bohr pictured electrons orbiting the positively charged nucleus similar to how the planets orbit the sun. while this picture was not entirely correct, it provides a good framework in which to make calculations about the energies of electrons. different from the predictions of newtonian mechanics, which allows any energy to be possible, bohr described the electron orbits (now called orbitals) as having specific energies. rank the following electron energy states according to their electron energies.
rank from highest to lowest energies.
- first excited state- ground state
- third excited state
- second excited state

The energetic order third excited > seconds excited > first excited > ground
Explanation:
Bohr's atomic model includes an integer that is responsible for the quantization of energy
E = - 13.6 /n² eV
Where n is the so-called principal quantum number, it is an integer with values of
n = 1, 2, 3… inf
For n = 1 have the so-called ground state that is the one with the lowest energy, for the minus sign in the formula E1 = -13.6 eV
For n = 2 it is the first excited state has the most energy than the ground state,
E2 = 13.6 / 4 = -3.4eV
For n = 3 we have the second excited state, E3 = -13.6 / 9 = -1.5 eV
For n = 4 we have the third excited state, E4 = -0.85 eV
The energetic order of the states is
E4 > E3 > E2 >E1
