This causes line emission spectra ... This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of atoms have different energy ...

A free atom is one which experiences no forces from neighbouring atoms. The Bohr model (named after Danish physicist Niels Bohr) of an atom has a small, positively charged central nucleus and ...

Optical Emission Spectroscopy (OES) is a technique used to determine the elemental composition of a wide range of metals. All OES analyzers contain the same main parts. An electrical source excites ...

Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

This book goes on to investigate the hydrogen atomic emission spectrum and how it dovetails into our understanding of quantum numbers to describe the energy, angular momentum, magnetic moment and spin ...
