difference between the two energy levels. Spectroscopes can be used to determine the unique electronic spectrum for each element, a result of the individual and discrete arrangement of electrons around each atom. Objectives: 1. Observe the emission spectra of various elements and 2. Use the ...
It helps to identify elements in the astronomical object by studying their spectra. Astronomers can measure the spectrum of light from a star to know the elements of the star. Each element emits light at a particular wavelength, therefore astronomers can find out what elements made up the stars...
The emission lines in the spectra are narrow because the transitions occur between distinct energy levels. AES excites all the atoms in a sample simultaneously; therefore, they can be detected simultaneously and this is a major advantage of AES compared to atomic-absorption; high resolution is ...
which have partially overlappingemission spectrabut lifetimes of 4 and 11.7 ns, respectively. The TRES of such a mixture shows contributions from both species. However, the relative contributions of the two keep varying. The decay-associated spectra will, however, be obtained with each spectrum belo...

or a diffraction grating, you can see distinct, coloured lines. This type of spectrum is called a line spectrum or an emission spectrum. Chemists first observed spectra like this in the mid-1800s. Question Can the Rutherford model of the atom explain the emission spectra of elements?
