Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons. It is not concerned with the formation of <a href="/wiki/Molecule" title="Molecule">molecules</a> (although much of the physics is identical), nor does it examine atoms in a <a href="/wiki/Solid-state_physics" title="Solid-state physics">solid state</a> as <a href="/wiki/Condensed_matter" class="mw-redirect" title="Condensed matter">condensed matter</a>. It is concerned with processes such as <a href="/wiki/Ionization" title="Ionization">ionization</a> and <a href="/wiki/Excited_state" title="Excited state">excitation</a> by photons or collisions with atomic particles. </p><p>While modelling atoms in isolation may not seem realistic, if one considers atoms in a <a href="/wiki/Gas" title="Gas">gas</a> or <a href="/wiki/Plasma_(physics)" title="Plasma (physics)">plasma</a> then the time-scales for atom-atom interactions are huge in comparison to the atomic processes that are generally considered. This means that the individual atoms can be treated as if each were in isolation, as the vast majority of the time they are. By this consideration, atomic physics provides the underlying theory in plasma physics and <a href="/wiki/Atmospheric_physics" title="Atmospheric physics">atmospheric physics</a>, even though both deal with very large numbers of atoms. </p> <div class="mw-heading mw-heading2"><h2 id="Electronic_configuration">Electronic configuration</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Atomic_physics&action=edit&section=2" title="Edit section: Electronic configuration"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Electrons form notional <a href="/wiki/Electron_shells" class="mw-redirect" title="Electron shells">shells</a> around the nucleus.

The energy necessary to remove an electron from its shell (taking it to infinity) is called the <a href="/wiki/Binding_energy" title="Binding energy">binding energy</a>.

After a certain time, the electron in an excited state will "jump" (undergo a transition) to a lower state. In a neutral atom, the system will emit a photon of the difference in energy, since energy is conserved. </p><p>If an inner electron has absorbed more than the binding energy (so that the atom ionizes), then a more outer electron may undergo a transition to fill the inner orbital. In this case, a visible photon or a <a href="/wiki/Characteristic_x-ray" class="mw-redirect" title="Characteristic x-ray">characteristic X-ray</a> is emitted, or a phenomenon known as the <a href="/wiki/Auger_effect" title="Auger effect">Auger effect</a> may take place, where the released energy is transferred to another bound electron, causing it to go into the continuum. The Auger effect allows one to multiply ionize an atom with a single photon. </p><p>There are rather strict <a href="/wiki/Selection_rule" title="Selection rule">selection rules</a> as to the electronic configurations that can be reached by excitation by light — however, there are no such rules for excitation by collision processes. </p> <div class="mw-heading mw-heading2"><h2 id="History_and_developments">History and developments</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Atomic_physics&action=edit&section=3" title="Edit section: History and developments"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Atomic_theory" class="mw-redirect" title="Atomic theory">Atomic theory</a></div> <p>One of the earliest steps towards atomic physics was the recognition that matter was composed of <i>atoms</i>. It forms a part of the texts written in 6th century BC to 2nd century BC, such as those of <a href="/wiki/Democritus" title="Democritus">Democritus</a> or <i><span title="Sanskrit-language text"><i lang="sa-Latn"><a href="/wiki/Vai%C5%9Be%E1%B9%A3ika_S%C5%ABtra" title="Vaiśeṣika Sūtra">Vaiśeṣika Sūtra</a></i></span></i> written by <span title="Sanskrit-language text"><span lang="sa-Latn" style="font-style: normal;"><a href="/wiki/Ka%E1%B9%87%C4%81da_(philosopher)" class="mw-redirect" title="Kaṇāda (philosopher)">Kaṇāda</a></span></span>. This theory was later developed in the modern sense of the basic unit of a <a href="/wiki/Chemical_element" title="Chemical element">chemical element</a> by the British chemist and physicist <a href="/wiki/John_Dalton" title="John Dalton">John Dalton</a> in the 18th century. At this stage, it wasn't clear what atoms were, although they could be described and classified by their properties (in bulk). The invention of the <a href="/wiki/Periodic_system_of_elements" class="mw-redirect" title="Periodic system of elements">periodic system of elements</a> by <a href="/wiki/Dmitri_Mendeleev" title="Dmitri Mendeleev">Dmitri Mendeleev</a> was another great step forward. </p><p>The true beginning of atomic physics is marked by the discovery of <a href="/wiki/Spectral_line" title="Spectral line">spectral lines</a> and attempts to describe the phenomenon, most notably by <a href="/wiki/Joseph_von_Fraunhofer" title="Joseph von Fraunhofer">Joseph von Fraunhofer</a>. The study of these lines led to the <a href="/wiki/Bohr_atom_model" class="mw-redirect" title="Bohr atom model">Bohr atom model</a> and to the birth of <a href="/wiki/Quantum_mechanics" title="Quantum mechanics">quantum mechanics</a>. In seeking to explain atomic spectra, an entirely new mathematical model of matter was revealed. As far as atoms and their electron shells were concerned, not only did this yield a better overall description, i.e. the <a href="/wiki/Atomic_orbital_model" class="mw-redirect" title="Atomic orbital model">atomic orbital model</a>, but it also provided a new theoretical basis for <a href="/wiki/Chemistry" title="Chemistry">chemistry</a> (<a href="/wiki/Quantum_chemistry" title="Quantum chemistry">quantum chemistry</a>) and <a href="/wiki/Spectroscopy" title="Spectroscopy">spectroscopy</a>. </p><p>Since the <a href="/wiki/World_War_II" title="World War II">Second World War</a>, both theoretical and experimental fields have advanced at a rapid pace. This can be attributed to progress in computing technology, which has allowed larger and more sophisticated models of atomic structure and associated collision processes. Similar technological advances in accelerators, detectors, magnetic field generation and <a href="/wiki/Laser" title="Laser">lasers</a> have greatly assisted experimental work. </p> <div class="mw-heading mw-heading2"><h2 id="Significant_atomic_physicists">Significant atomic physicists</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Atomic_physics&action=edit&section=4" title="Edit section: Significant atomic physicists"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1184024115">.mw-parser-output .div-col{margin-top:0.3em;column-width:30em}.mw-parser-output .div-col-small{font-size:90%}.mw-parser-output .div-col-rules{column-rule:1px solid #aaa}.mw-parser-output .div-col dl,.mw-parser-output .div-col ol,.mw-parser-output .div-col ul{margin-top:0}.mw-parser-output .div-col li,.mw-parser-output .div-col dd{page-break-inside:avoid;break-inside:avoid-column}</style><div class="div-col" style="column-width: 30em;"> <dl><dt>Pre quantum mechanics</dt></dl> <ul><li><a href="/wiki/John_Dalton" title="John Dalton">John Dalton</a></li> <li><a href="/wiki/Joseph_von_Fraunhofer" title="Joseph von Fraunhofer">Joseph von Fraunhofer</a></li> <li><a href="/wiki/Johannes_Rydberg" title="Johannes Rydberg">Johannes Rydberg</a></li> <li><a href="/wiki/J._J._Thomson" title="J.
