WebAug 10, 2015 · Line emission can actually occur at any energy of light (i.e. visible, UV, etc. ) and with any type of atom. However, not all atoms have line emission at all wavelengths. The difference in energy between levels in the atom is not great enough for the emission to be X-rays in atoms of lighter elements, for example. Continuum Emission WebExcited energy lovels are labeled n = 2, n = 3, etc. Arrows correspond to the possible emission pathways. Each pathway corresponds to a single line in the emission spectrum. Only the Balmer series is visible. Elnure 1: Enerav level diagram for the hydrogen atom.
