Line up the lines to identify the unknown elements.
(b) the light emitted as an atomic electron makes a transition from one atomic state to another. Is can be used to identify an element in mixtures. A spectral line represents (a) the energy of an electron in an atom. Since each element has different numbers of protons, neutrons and most importantly electrons, the emission spectrum for each element is different.
Line spectra series#
This series is referred to as the Lyman Series.įurther the electron falls, the more energy it releases. This series is called the Balmer series.Įlectron falls to the 1st energy level, the light given off is t=in the Is in the visible region of the spectrum and spectral line of color are Series of electron transitions is referred to as the Paschen series.Įlectron falls to the 2nd energy principal energy level, the light given off Level, the light given off is in the infrared region of the spectrum. These lines can tell us how many energy levels an atom has and how far away they.

Hydrogen atom, if the electron falls to the 3rd energy principal energy The lines in spectra are caused by electrons moving in between energy levels. It is when they return to the ground state energy is given off.īut electrons don't have to go directly there. Ground state (lowest energy configuration)Įxcited State (higher energy configuration)Ģ-6-1 **Note the # of electrons are the same This is not the cause of the spectral lines. Line spectra of either type are useful in chemical analysis, since they reveal the presence of particular elements. "Excite electrons fall back to lower energy levels releasing energy in the form of light."Įxciting an electron promotes it to a higher sublevel of energy level.
