Emission spectrum energy diagram
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an electron making a transition from a high energy state to a lower energy state. The photon energy of the emitted photon is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each t… Webnation of the spectrum of helium, it is necessary to consult works on atomic physics somewhat beyond the introductory level. I have found Herzberg’s book Atomic Spectra and Atomic Structure4 very useful and include here the energy-level diagram for helium (see Fig. 2) from this work. Although the diagram is much more complex than the analogous

WebEmission spectrum definition, the spectrum formed by electromagnetic radiations emitted by a given source, characteristic of the source and the type of excitation inducing the … WebExplain the emission spectra. When energy is supplied to an atom, electrons gain energy and jump to higher energy levels from ground state to an excited state. However, they can't remain at excited state so they drop to lower levels and emit energy. The energy emitted corresponds to a wavelength and shows up as a line in the spectrum.
WebEmission spectra. If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in ...
