Rydberg formula

1. Rydberg formula Rydberg's formula enumerates the spectral energy variations of electron transitions with their wavelengths. The estimation of wavelengths of spectral energies helps to identify the spectral emission lines of the hydrogen line spectrum. The Rydberg formula is applicable to hydrogenic atoms of chemical elements. It means the elements with a single electron like hydrogen. Examples of such single- electron systems are He+, Li2+, Be3+, etc. Additionally, the Rydberg formula for other single- electron species involves Z for precise spectral evaluations. Rydberg's experiments on alkali metal spectra presented a successful spectral formula to calculate the wavenumber of photons. We all know hydrogen is the first element of the alkali metal group, so applying the Rydberg formula to hydrogen became a center of attraction due to its abundance. one of the innermost 1S- electrons are taken away from the atom due to electron bombardment. It leaves a core hole in the lowest Bohr orbit. To fill this vacancy, one electron from a higher 2P- orbital jump to a 1S-orbital by emitting X-rays. Moseley found an empirical relationship between the emerged X- rays of the atom and their atomic number. Surprisingly, it resembles the Rydberg equation closely by replacing Z with (Z-1) for elements other than hydrogen. Rydberg formula applies to all spectral series of the hydrogen spectrum, including the Balmer series, due to its correctness in spectral measurements. Even though the Rydberg formula is an empirical generalization of the Balmer formula and hence the common name is used Rydberg- Balmer formula for the Balmer series. Even though the Rydberg formula was discovered in 1888, it did not get much practical significance until Neil Bohr explained its theoretical meaning. In 1913, the Danish physicist Neil Bohr explained the cause of electromagnetic emissions of atoms satisfactorily. Blog: https://jayamchemistrylearners.blogspot.com/
