Hann stakk því upp á að vetniskjarninn, sem vitað var að hefði atómtöluna 1, væri öreind. Þessa öreind kallaði hann róteind. </p> <div class="mw-heading mw-heading2"><h2 id="Tæknileg_not"><span id="T.C3.A6knileg_not"></span>Tæknileg not</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=R%C3%B3teind&veaction=edit&section=3" title="Breyti hluta: Tæknileg not" class="mw-editsection-visualeditor"><span>breyta</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=R%C3%B3teind&action=edit&section=3" title="Edit section's source code: Tæknileg not"><span>breyta frumkóða</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Róteindir geta verið til í mismunandi spunaástandi.
