Which color corresponds to 6? 2 transition? 5? 2 transition? 4? 2 transition? 3? 2 transition? explain your reasoning.

The transition 6→2, corresponds to the color violet.

The transition 5→2, corresponds to the color blue.

The transition 4→2, corresponds to the color aqua or greenish-blue.

The transition 3→2, corresponds to the color red.

Explanation:

The Balmer series is the second spectral series in the emission spectrum of the hydrogen atom. This series includes the transition from an outer orbit having principal quantum number, n ≥ 3 to orbit having n = 2.

As energy (E) is inversely proportional to wavelength (λ) by the equation, E=hc/λ. So, high energy transition has lower wavelength and low energy transition has higher wavelength.

In the Balmer series:

The transition 6→2 is a high energy transition, so it corresponds to lower wavelength 410.17 and thus the color violet.

The transition 5→2, corresponds to wavelength 434.05 and thus the color blue.

The transition 4→2, corresponds to wavelength 486.14 and thus the color aqua or greenish-blue.

The transition 3→2 is a low energy transition, so it corresponds to higher wavelength 656.45 and thus the color red.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
