D'aquesta manera, la <a href="/wiki/Configuraci%C3%B3_electr%C3%B2nica" title="Configuració electrònica">configuració electrònica</a> del lawren-ci ha presentat certes controvèrsies perquè fins i tot molt recentment se li han assignat indistintament les configuracions 7<i>s</i><sup>2</sup>7<i>p</i><sup>1</sup> o 7<i>s</i><sup>2</sup>6<i>d</i><sup>1</sup>. Tot i això, l'any 2015 es calculà experimentalment el seu primer <a href="/wiki/Energia_d%27ionitzaci%C3%B3" title="Energia d'ionització">potencial d'ionització</a>, IP1 (4,96 eV a l'isòtop lawrenci 256). Aquest valor d'IP1 és significativament més baix que el del luteci i inferior al de tots els lantanoides i actinoides, de manera que es confirma la configuració de capa tancada 5<i>f</i><sup>14</sup> i 7<i>s</i><sup>2</sup> amb un electró addicional dèbilment enllaçat a l'orbital de valència. Els càlculs teòrics realitzats considerant els efectes relativistes concorden amb aquest valor i prediuen un valor del nivell 7<i>s</i><sup>2</sup>7<i>p</i><sub>1/2</sub> del Lr ~ 180 meV inferior que el del nivell 7<i>s</i><sup>2</sup>6<i>d</i><sub>3/2</sub>, i semblen confirmar la primera com la configuració electrònica de l'element. Aquest fet ha suscitat diferents propostes per a la ubicació del lawrenci a la <a href="/wiki/Taula_peri%C3%B2dica" title="Taula periòdica">taula periòdica</a>: bé al grup 3 al costat del Sc, Y i Lu, o bé al final del bloc f, amb dues sèries de quinze elements: La–Lu i Ac –Lr. Els estudis realitzats en models simples de monohidrurs i trihidrurs, monocarbonils o triclorurs apunten aquesta darrera possibilitat perquè suggereixen que no hi ha diferències químiques significatives entre el Lr i altres lantanoides. De fet, la IUPAC, a fi d'afrontar aquesta qüestió, creà un grup de treball l'any 2015 per establir una recomanació en l'elecció dels elements que han de conformar el grup 3.<sup id="cite_ref-:3_6-3" class="reference"><a href="#cite_note-:3-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Nucleosíntesi"><span id="Nucleos.C3.ADntesi"></span>Nucleosíntesi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Lawrenci&action=edit&section=5" title="Modifica la secció: Nucleosíntesi"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Fusió"><span id="Fusi.C3.B3"></span>Fusió</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Lawrenci&action=edit&section=6" title="Modifica la secció: Fusió"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt> <sup>205</sup>Tl(<sup>50</sup>Ti,xn)<sup>255-x</sup>Lr (x=2?)</dt></dl> <p>Aquesta reacció es va estudiar en una sèrie d'experiments el 1976 per <a href="/wiki/Iuri_Oganessian" title="Iuri Oganessian">Iuri Oganessian</a> i el seu equip al Laboratori Fliórov de Reaccions Nuclears (<abbr title="Laboratori Fliórov de Reaccions Nuclears">LFRN</abbr>).
