IB Chemistry Unit 2 SL Latest Version Graded A+ Emission spectrum ️️An emission spectrum is produced when an atom moves from a higher to a lower level. The line emission spectrum of hydrogen provides evidence for __________________ which converge at _____________ ️️The line emission spectrum of hydrogen provides evidence for the existence of electrons in discrete energy levels which converge at higher energies. Continuous spectrum ️️All the colours / wavelengths present merge smoothly into one another; A continuous spectrum is produced when white light source like the sun is passed through a prism. Line spectrum ️️A spectrum with only some discrete colours / wavelengths present. Shell ️️The main (principle) energy levels where the electrons are located Maximum # of e- in a main energy level ️️2n^2, with n being the energy level Subshell ️️A set of degenerate orbitals within a shell
