I know that each element does have a unique spectrum and that the spectrum can be used to classify an unknown element, but i cannot figure out WHY each element has this. Each of these spectral lines corresponds to a different electron transition from a higher energy state to a lower energy state. I think it does, but I'm not sure. What two competing fundamental forces are at work inside the nucleus of an atom? An emission spectrum is the electromagnetic radiation (EMR), such as visible light, a substance emits. When the substance emits light, a bright-line spectrum or an emission spectrum is generated (these look like a series of bright lines on a black background). Each element has a unique set of possible energy levels in which an electron can reside. 2. ... the wavelength of which refers to the discrete lines of the emission spectrum. Each element has its unique line emission spectrum. The reason why each atom has a unique emission spectra is because the atom has more or less attractive forces. 4. I am deeply confused!! Emission spectrum: The emission spectrum of a chemical compound or chemical element is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state. Note however that the emission extends over a range of frequencies, an effect called spectral line broadening. How can this technique be used to determine the elemental composition of stars? Each element emission spectrum is unique and have specific properties. Question 4: Nuclear Structure (5 points) A. 5. please help! The spacing between the lines in the spectrum of an element are constant. Here is a great sample from one of my students. Emission spectra are unique for each element (or different elements have different emission spectra). Basically. Every element gives off a unique fingerprint of light, so analyzing the frequencies of this light helps identify the chemical that generated it. It cannot be because of the number of electrons because the ions of an element still all have the same spectrum. Does a 40 W incandescent light bulb produce both a continuous and a line spectrum? Why does each element has a unique spectrum of absorption or emission lines. (2 points) Each element has a different number of protons therefore the energy needed is different for each element. Every element has a unique atomic emission spectrum, as shown by the examples of mercury (Hg) and strontium (Sr). Why do elements produce different numbers of spectral lines? For example, compare spectra of hydrogen: helium: and carbon: But why? C. Why does each element have its own unique emission spectrum? Was there any underlying reason for each element to generate a unique spectrum? We can observe the emission spectra of anything burning to determine what elements are contained therein. This is called the emission spectrum of an element. In order from lowest to highest frequency, the main bands are. 3. Johannes Balmer studied the optical spectrum of hydrogen and found a pattern in the wavelengths of its emission … As each Element has its own state of excitement. For example, Helium and Lithium + both have the same amount of electrons, but Helium has two protons, whereas Lithium has three, hence making the wavelength and spectrum different. Explain why each element has a unique spectrum of absorption or emission lines. why does each element have a unique line emmision spectrum? element emission spectra reflection.jpg.
