Deuteri

El deuteri, D o ²H<a href="#cite_note-1" style="counter-reset: mw-Ref 1;">[1]</a> és un dels <a href="/ca/Isòtops" title="Isòtops" class="mw-redirect wl">isòtops</a> estables de l'<a href="/ca/Hidrogen" title="Hidrogen" class="wl">hidrogen</a>. A diferència de la resta d'elements químics, els isòtops de l'hidrogen s'anomenen d'una manera específica: així, depenent de la composició del <a href="/ca/Nucli_atòmic" title="Nucli atòmic" class="wl">nucli atòmic</a>, es parla de:

<ul><li><a href="/ca/Proti" title="Proti" class="wl">proti</a> (H), fent referència a l'isòtop més comú, compost per un sol <a href="/ca/Protó" title="Protó" class="wl">protó</a> al nucli.;</li>
<li>de deuteri, isòtop que conté un protó i un <a href="/ca/Neutró" title="Neutró" class="wl">neutró</a>;</li>
<li>o de <a href="/ca/Triti" title="Triti" class="wl">triti</a>, que té un protó i dos neutrons (un neutró més que el deuteri).</li></ul>
