Atomic Orbitals, Electronic Configuration and the Periodic Table Flashcards
each element in a sample produces characteristic absorption and emission spectra. These spectra can be used to…
identify and quantify the element.
In absorption spectroscopy, electromagnetic radiation is…
directed at an atomised sample. Radiation is absorbed as electrons are promoted to higher energy levels.
An absorption spectrum is produced by…
measuring how the intensity of absorbed light varies with wavelength.
In emission spectroscopy, high temperatures are used to…
excite the electrons within atoms
As the electrons drop to lower energy levels…
photons are emitted.
An emission spectrum of a sample is produced by…
measuring the intensity of light emitted at different wavelengths
In atomic spectroscopy, the concentration of an element within a sample is related to…
the intensity of light emitted or absorbed.
