Emission spectroscopy can be used to identify elements by the emitted EM radiation from excited atoms. The excitation isually occurs in at high temperature eg an electric arc, plasma generation and the like. Many industrial analytical techniques for rapid analysis use this methodology. it is very common in the steel industry where rapid steel anlysis id required for production control.\n\nHelium was identified in the Sun by emission spectroscopy before it was identified on earth.

Very simply: Every element when heated gives off a radiation frequency that is specific to itself. When the entire spectrum of light from a star is analyzed, those frequencies representing specific elements are absorbed and show up as dark lines in specific areas. Each star has a unique pattern. After correcting for any red or blue shift ( discuss that another time), the same elements will appear in the same spectral region.

http://periodic.lanl.gov/default.htm\n\nClick on the element, and it's in the top section of information. To write out the electron configuration for every element would take quite a while, so if you need it for a specific element or a few elements, I'd reccomend asking just for the few.

almost certainly it would be in the visible region of the spectrum. after all it does have that pretty color!\nvisible region is roughly between 400-700 nanometers wavelength.

Atomic spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. Atomic spectroscopy is closely related to other forms of spectroscopy. It can be divided by atomization source or by the type of spectroscopy used. In the latter case, the main division is between optical and mass spectrometry. Mass spectrometry generally gives significantly better analytical performance, but is also significantly more complex. This complexity translates into higher purchase costs, higher operational costs, more operator training, and a greater number of components that can potentially fail. Because optical spectroscopy is generally less expensive and has performance adequate for many tasks, it is far more common. Atomic absorption spectrometers are one of the most commonly sold and used analytical instruments.\n\nFind out more here: \nhttp://en.wikipedia.org/wiki/Atomic_spectroscopy

Actually, this is a really hard one: color arises from light having different frequencies, and the different colors are reflected with varying efficiency from various substances: so a red color arises from a substance that reflects well low frequencies (red) and absorbs higher ones (blue and yellow).\n\nNow what determines in which way a given substance reflects light at different frequencies? That varies a lot: for starters, some atoms *are* in fact colored, that is, they reflect one frequency more  than another: chlorine gas is an example. This is also frequently the case for molecules (dyes). On the other hand, it is also often caused by some effect that cannot be traced back to the individual parts that make up the whole: think of a sand heap: clearly, none of the grains is a heap, nor is there any specific grain which gives the heap its peculiar properties. What makes a sand heap is just the large number of grains, all acting mutually one upon the other. A crowd, similarly, often does things you cannot really explain in terms of the individuals that make it up. Similarly, for example, a large number of copper atoms find a weird way of reflecting certain frequencies much more than others: it is a property of the whole substance that cannot be reduced to the individual copper atoms. Color, by the way, is not at all the only such property.

All elements when heated give off a signature in the light spectrum. For example if you heated a piece of pure iron until it glowed then put a prism in front  of the light, you would see the spectrum of light -- obvious stuff. However because it is the metal iron there would be slots-- frequencies that would be missing. These signatures are all very different from each other depending on which element(s) are giving off light. When something is red shifted the signature is still there but it's place in the spectrum is in the wrong place. It has shifted to the red end of the spectrum-- it is in the longer or red end of it.\n\nThere is two ways to think of this, the other is that when heated elements will give off light in only so many frequencies- the rest of the frequencies are missing.

All elemets will give of colors when excited enough. Some take extremely high energy. Elements can be idntified by these colors. Some elements give off their colors easily, such as the metals in column 1 and 2 and copper. When placed in a flame the outer electrons jump to a higher energy level and when they fall back they fall a specific distance or wavelength. . We see it as the color we perceive.

A two-color three-photon ionization technique, using two pulsed dye lasers, was employed to explore the high-lying energy levels of U I. A number of new U I levels in the 34 290--35 120-cm/sup -1/ region was observed.^Uncertainty in the assignment of J values to some levels known from earlier studies was also reduced or removed.\n\nHUH? Is that what you want?\n\nEDIT\nAbstract. Two-colour resonance ionization spectroscopy was used for identification of 240 new levels of 238U in the energy range of 38 500 to 41 200 cm-1. A precision of +or-0.03 cm-1 (1 SD) for the energies was obtained by using laser-induced fluorescence signals of I2 for spectral calibration. The angular momentum quantum number, J, was uniquely assigned for 134 of these levels by using angular momentum selection rules. \n\nThats a little more specific\nAnd some more\n\nAbstract. Visible and infrared absorption measurements on the  ion in tetragonal zircon-type matrix  are reported and analysed in terms of the standard parametrization scheme. The observed 17 main peaks and a number of less intense lines have been assigned and fitted to most of the 32 allowed electric dipole transitions with the root mean square error equal to . The free-ion parameters obtained for the model Hamiltonian, , ,  and , as well as the corresponding crystal-field parameters, , , ,  and , agree fairly well with the initial theoretical estimations. The results are discussed in relation to the previous spectroscopic study on the scheelite-type matrix .

Since the spectra of a given element shows a discrete number of color bands (rather than a continuous specturm), and since the color of light relates to its energy, and since photons are released by the relaxation of electrons from a higher to a lower energy state, it follows that the gaps between energy levels are distinct and finite.  This means that the energy levels are quantized.

so you plot the proton number on the y-axis, and the different melting points of the elements across the x- axis.. actually are sure it has to be a bar graph.. i think a line/scatter graph would be more accurate maybe?

All elements (atoms) absorb and reflect certain frequencies(colors) of light. This spectra can be used to identify the elements present in a sample of material even if it is a neutron star a billion light years away or a piece of lint on a table.

By the process called spectroscopy. It is the separation of light spectrum by different methods (a prism more often). Now, a type of atom, like helium for example, will absorb a small wave light in the light spectrum (this appearing to us like a thin, black, vertical line). Every atom type absorbs different light Wave. By knowing the spectrum of every single atom, we can superpose them and "see" who's`s who, only by having sun light

A spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. The independent variable is usually the wavelength of the light, normally expressed as some fraction of a meter, but sometimes expressed as some unit directly proportional to the photon energy, such as wave number or electron volts, which has a reciprocal relationship to wavelength. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. Spectrometer is a term that is applied to instruments that operate over a very wide range of wavelengths, from gamma rays and X-rays into the far infrared.\n\nThe readings on the spectrograph tells what the chemical make up of that object...
