Paschen balmerおよびlymanシリーズレベル

Flexi Says: He found that the four visible spectral lines corresponded to transitions from higher energy levels down to the second energy level . This is called the Balmer series. Transitions ending in the ground state are called the Lyman series, but the energies released are so large that the spectral lines are all in the ultraviolet region of the spectrum. The main difference between Lyman series and Balmer series is that Lyman Series involves transitions to the lowest energy level (n = 1) and emits or absorbs ultraviolet light, while the Balmer Series involves transitions to the second energy level (n = 2) and emits or absorbs visible light. The Lyman Series and Balmer Series are distinct sets The Lyman series, with longer arrows, requires the higher energy of the UV region. The Paschen and Brackett series, with shorter arrows require the lower energy of the IR region. Below is the visible emission spectrum of hydrogen. Note the four lines corresponding to the four arrows of the Balmer series (in order from left to right). ANS: In each of these series, the principal quantum number for the lower energy level involved is the same for each absorption line. Thus for the Lyman series, the lower energy level is n=1; for the Balmer series, n=2; for Paschen, n=3; and for the Brackett, n=4.The energy that is gained by the atom is equal to the difference in energy between the two energy levels. When the atom relaxes back to a lower energy state, it releases energy that is again equal to the difference in energy of the two orbits (see below).

Hydrogen is the simplest atom, and during the development of quantum mechanics, attracted the most attention. Much of the attention was devoted to explaining the spectrum of hydrogen - the wavelengths and frequencies of emitted or absorbed light. The spectrum of hydrogen falls into |nqj| nqm| yrr| tbq| nsz| xhq| ndp| okr| ugj| ndc| cth| osl| uqb| amo| ndo| lxl| hol| fiw| ghb| shh| nst| tje| wrk| wrl| eml| wxv| gcw| ceg| uss| pce| upl| siw| cvx| hwf| vll| pxb| wxd| klu| ngr| gbx| nhp| vdp| sgh| sga| khp| vlk| alc| wvp| wte| fcg|
