According to the bohr model of the atom, which electron transition would correspond to the shortest wavelength line in the visible emission spectra for hydrogen?

Explanation:

According to Bohr's model, electrons are travelled in defined circular orbit around the nucleus. The orbits of different energy level is labelled by quantum numbers (n). Electrons can jump different energy levels, from higher to lower energy level by releasing energy.

In the visible emission spectrum of hydrogen, there are mainly five series which we are studied in regular. Series are: Lyman series(n=1), Balmer series(n=2), Paschen series(n=3), Bracket series(n=4), Pfund series(n=5).

Wavelength is inversely proportional to the quantum number(n). So, we can conclude that greater the value of n shortest the wavelength. According to above spectral series Pfund series(n=5) have shortest wavelength.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
