Document Summary
Emission spectra and electronic structure of atoms: the h spectrum. Measure the wavelengths of the visible lines in the hydrogen spectrum using a spectroscope. Visualize emission spectra of salt solutions, k+, ca2+ and li+ When electrons get excited they move to a high energy state (absorb energy). This energy can be provided by heat, light or an electrical discharge. Photons of light are emitted when the atom goes from a higher energy state (nh) to a lower energy state (nl) Balmer series when nl = 2, lies in visible region. Lyman series hydrogen spectral series of transitions, results in uv emission lines. Colour of light emitted by a specific atom depends on how much energy the electron releases as it moves down to a lower energy level. Spectrum set of individual colours emitted by an element. General equation suggested by rydberg in 1890: (cid:1874)= (cid:2869)= (cid:4666) (cid:2869)(cid:3041) .
