Practise using hydrogen's line spectrum as evidence for discrete electron energy levels. Identify transitions ending at different principal levels, explain photon emission and…
Lithium and boron are elements in period 2 of the periodic table. Lithium occurs in group 1 (the alkali metals) and boron occurs in group 3. Isotopes exist for both elements.
Every element has its own unique line emission spectrum.
Draw a diagram to show the electron transitions between energy levels in a hydrogen atom that are responsible for the two series of lines in the ultraviolet and visible regions of the spectrum. Label your diagram to show three transitions for each series.
