nuklidkarta.</figcaption></figure> <p>En <b>isotop</b> av ett <a href="/wiki/Grund%C3%A4mne" title="Grundämne">grundämne</a> är en variant med ett specifikt antal <a href="/wiki/Neutron" title="Neutron">neutroner</a>. <a href="/wiki/Atomslag" title="Atomslag">Atomslaget</a> bestäms av antalet <a href="/wiki/Proton" title="Proton">protoner</a> i kärnan, <a href="/wiki/Atomnummer" title="Atomnummer">atomnumret</a>, och är avgörande för <a href="/wiki/Elektronkonfiguration" title="Elektronkonfiguration">elektronkonfigurationen</a>, och därmed de kemiska egenskaperna hos ett ämne. I kärnan finns också för de flesta grundämnen neutroner, som påverkar de kemiska egenskaperna i långt mindre grad. Olika isotoper av samma ämne har därför vanligen nästan helt identiska kemiska egenskaper, även om <a href="/wiki/Masstal" title="Masstal">masstalet</a> skiljer. </p><p>Skillnaderna i masstal kan dock innebära att vissa fysikaliska egenskaper, som <a href="/wiki/Densitet" title="Densitet">densitet</a>, smältpunkt och <a href="/wiki/Kokpunkt" title="Kokpunkt">kokpunkt</a>, är olika. För <a href="/wiki/V%C3%A4te" title="Väte">väte</a>, där atommassan är låg från början, påverkar också skillnaden i massa mellan vanligt och <a href="/wiki/Deuterium" title="Deuterium">tungt väte</a> de kemiska egenskaperna något. Dessutom varierar atomkärnans stabilitet kraftigt mellan olika isotoper, varför man vanligen bara kan hitta ett fåtal olika isotoper av ett ämne i naturen. Andra isotoper kan skapas i laboratorier, men är då radioaktiva. </p><p>För lättare atomslag är antalet neutroner i kärnan ungefär lika med antalet protoner. Tyngre grundämnen har en högre andel neutroner vilket ses i nuklidkartan. </p><p>Ordet isotoper används ibland oegentligt i stället för nuklider.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-reference-link-bracket">[</span>1<span class="cite-reference-link-bracket">]</span></a></sup> Begreppet nuklid syftar i första hand på nukleära egenskaper framför kemiska egenskaper, medan begreppet isotop främst syftar på kemiska egenskaper framför nukleära. När man fokuserar på en bestämd typ av atomkärna och dess egenskaper, till exempel i kärnreaktioner, väljer man lämpligast <i>nuklid</i>. När det handlar om att gruppera olika slags atomer av ett visst grundämne är <i>isotop</i> det mer adekvata begreppet. </p><p>Som exempel visar nuklidkartan att grundämne nummer 50 – <a href="/wiki/Tenn" title="Tenn">tenn</a> - har 7 stabila isotoper (svarta rutor) och ytterligare 31 instabila isotoper (orange och blå rutor). Kartan visar också att det finns 3 stabila nuklider (<sup>88</sup>Sr, <sup>89</sup>Y och <sup>90</sup>Zr) med neutronantalet 50. För de två sistnämnda finns det dock även de radioaktiva <a href="/wiki/K%C3%A4rnisomer" title="Kärnisomer">kärnisomererna</a> <sup>89m</sup>Y och <sup>90m</sup>Zr vilka inte markeras i kartan. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Stabila_isotoper">Stabila isotoper</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Isotop&veaction=edit&section=1" title="Redigera avsnitt: Stabila isotoper" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Isotop&action=edit&section=1" title="Redigera avsnitts källkod: Stabila isotoper"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Stabila isotoper är isotoper som inte genomgår <a href="/wiki/Radioaktivt_s%C3%B6nderfall" class="mw-redirect" title="Radioaktivt sönderfall">radioaktivt sönderfall</a>.

De flesta isotoper är radioaktiva, men eftersom de flesta radioaktiva isotoper har halveringstider som är betydligt kortare än jordens ålder och sönderfallskedjor alltid avslutas med någon stabil isotop, består huvuddelen av materien på jorden av stabila isotoper. Ett <a href="/wiki/Grund%C3%A4mne" title="Grundämne">grundämne</a> kan sakna stabila isotoper, eller ha en enda stabil isotop (vara <i>monoisotopt</i>) eller flera. Den tyngsta kända stabila isotopen är <a href="/wiki/Bly" title="Bly">bly</a>-208. </p><p>För de flesta grundämnen med flera isotoper är en stabil isotop dominerande i naturen. Detta gör att de flesta grundämnen har en <a href="/wiki/Atommassa" title="Atommassa">atommassa</a> som ligger nära ett heltal. Ett undantag är <a href="/wiki/Klor" title="Klor">klor</a> med en atommassa på 35,5 u, eftersom naturligt klor består av ¾ <sup>35</sup>Cl och ¼ <sup>37</sup>Cl. </p><p>Kunskapen om huruvida en isotop är stabil eller inte, grundar sig på mätningar av dess sönderfall. Det innebär att vissa av de isotoper som idag räknas som stabila, kan tänkas ha ett mycket långsamt sönderfall, som ännu inte kunnat observeras. </p> <div class="mw-heading mw-heading2"><h2 id="Instabila_isotoper">Instabila isotoper</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Isotop&veaction=edit&section=2" title="Redigera avsnitt: Instabila isotoper" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Isotop&action=edit&section=2" title="Redigera avsnitts källkod: Instabila isotoper"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Många isotoper finns men är instabila, det vill säga att de genomgår <a href="/wiki/Radioaktivt_s%C3%B6nderfall" class="mw-redirect" title="Radioaktivt sönderfall">radioaktivt sönderfall</a>.

I många fall uppstår på så sätt en ny instabil isotop som sönderfaller vidare. På så vis bildas en <a href="/wiki/S%C3%B6nderfallskedja" title="Sönderfallskedja">sönderfallskedja</a>.
