7/30/2023 0 Comments Line spectra definitionA bright line spectrum is a class of spectra referred to as an emission spectrum. Because a hydrogen atom with its one electron in this orbit has the lowest possible energy, this is the ground state (the most stable arrangement of electrons for an element or a compound) for a hydrogen atom. Become a member to unlock this answer Create your account. Spectral lines are often used to identify atoms and molecules. In the case of an emission spectrum, the atom is first excited by a colliding electron. A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. When a photon is absorbed by a hydrogen atom, the energy of the photon causes the electron to undergo a transition to a higher energy level (n 1 n 2, for example). These series of radiations are named after the scientists who discovered them. at a lower potential energy) when they are near each other than when they are far apart. Distinguish between emission and absorption line spectra. The hydrogen emission spectrum consists of radiations of discrete frequencies. \) indicates that the electron-nucleus pair is more tightly bound (i.e. Emission line spectra are produced by hot, low pressure gases The emission spectrum of hydrogen.
