Ei au studiat, sub îndrumarea lui <a href="/wiki/Ernest_Rutherford" title="Ernest Rutherford">Ernest Rutherford</a>, <a href="/w/index.php?title=%C3%8Empr%C4%83%C8%99tierea_particulelor_%CE%B1&action=edit&redlink=1" class="new" title="Împrăștierea particulelor α — pagină inexistentă">împrăștierea particulelor α</a> la trecerea printr-o foiță subțire din <a href="/wiki/Aur" title="Aur">aur</a>. Conform modelului atomic elaborat de <a href="/wiki/J.J._Thomson" class="mw-redirect" title="J.J. Thomson">Thomson</a>, particulele trebuiau să fie deviate cu câteva grade la trecerea prin metal din cauza <a href="/wiki/For%C8%9Ba_electrostatic%C4%83" class="mw-redirect" title="Forța electrostatică">forțelor electrostatice</a>. S-a constatat, însă, că unele dintre ele erau deviate cu <a href="/wiki/Unghi" title="Unghi">unghiuri</a> mai mari decât 90° sau chiar cu 180°. Acest fapt a fost explicat prin existența unei neuniformități a distribuției de <a href="/wiki/Sarcin%C4%83_electric%C4%83" title="Sarcină electrică">sarcină electrică</a> în interiorul atomului. Pe baza observațiilor efectuate, Rutherford a propus un nou model în care sarcina pozitivă era concentrată în centrul atomului, iar electronii orbitau în jurul acesteia. </p><p> Noul model introducea noțiunea de <a href="/wiki/Nucleu_atomic" title="Nucleu atomic">nucleu</a>, fără a-l numi astfel. Rutherford se referea, în lucrarea sa din <a href="/wiki/1911" title="1911">1911</a>, la o concentrare a sarcinii electrice pozitive:</p><blockquote><p><i>"Se consideră trecerea unei particule de mare viteză printr-un atom având o sarcină pozitivă centrală </i>N e<i>, compensată de sarcina a </i>N<i> electroni."</i></p></blockquote><p> El a estimat, din <a href="/w/index.php?title=Conservarea_energiei&action=edit&redlink=1" class="new" title="Conservarea energiei — pagină inexistentă">considerente energetice</a>, că, pentru atomul de aur, aceasta ar avea o rază de cel mult 3.4 x 10<sup>-14</sup> <a href="/wiki/Metru" title="Metru">metri</a> (valoarea actuală este egală cu aproximativ o cincime din aceasta). Mărimea razei atomului de <a href="/wiki/Aur" title="Aur">aur</a> era estimată la 10<sup>-10</sup> metri, de aproape 3000 de ori mai mare decât cea a nucleului. </p><p>Rutherford a presupus că mărimea sarcinii pozitive ar fi proporțională cu <a href="/wiki/Mas%C4%83_atomic%C4%83" title="Masă atomică">masa atomică</a> exprimată în <a href="/wiki/Unitate_atomic%C4%83_de_mas%C4%83" title="Unitate atomică de masă">unități atomice</a>, având jumătate din valoarea acesteia. A obținut pentru aur o masă atomică de 196 (față de 197, valoarea actuală). El nu a făcut corelația cu <a href="/wiki/Num%C4%83r_atomic" title="Număr atomic">numărul atomic</a> Z, estimând valoarea sarcinii la 98 <i>e</i>, față de 79, unde <i>e</i> reprezintă sarcina electronului. </p><p>Modelul propus de Rutherford descrie nucleul, dar nu atribuie nici o structură <a href="/wiki/Orbit%C4%83" class="mw-disambig" title="Orbită">orbitelor</a> electronilor.
