7 Atomic Emission Theory This high-temperature atomisation source provides sufficient energy to promote the atoms into high energy levels. When the atoms decay back to lower levels, they simultaneously emit light in the form of a photon Atom Ion M M + + photon State I + photon State II 7
8 Atomic Emission explained Atomic Emission the wavelength regions Spectral Region Vacuum UV Ultra-Violet Visible Near IR Wavelength = nm Lower wavelengths are shorter and have more energy, higher wavelengths e.g. in the Visible region, are longer and have less energy 8
9 Inductively Coupled Plasma (ICP) Quartz torch surrounded by induction coil Magnetic coupling to ionized gas High temperature equivalent to 10,000k 9

ELECTRON CONFIGURATION (SHORT FORM) # of electrons in the subshell. valence electrons Valence electrons have the largest value for "n"!
179 ELECTRON CONFIGURATION (SHORT FORM) - We can represent the electron configuration without drawing a diagram or writing down pages of quantum numbers every time. We write the "electron configuration".
It takes four quantum numbers to describe an electron. Additionally, every electron has a unique set of quantum numbers.
So, quantum mechanics does not define the path that the electron follows; rather, quantum mechanics works by determining the energy of the electron. Once the energy of an electron is known, the probability
