Hauptgruppe, ist unter Normalbedingungen ein Nichtmetall und wird deshalb nicht zu den Alkalimetallen gezählt. Wasserstoff hat z. B wie andere typische Nichtmetalle eine deutlich höhere erste <a href="/wiki/Ionisierungsenergie" title="Ionisierungsenergie">Ionisierungsenergie</a> als die Alkalimetalle, die ihr Elektron leicht abgeben, und zeigt dementsprechend andere chemische Eigenschaften. Anders als die Alkalimetalle teilt Wasserstoff sein Elektron mit Nichtmetallen wie Chlor oder Sauerstoff und bildet mit ihnen über <a href="/wiki/Kovalente_Bindung" title="Kovalente Bindung">kovalente Bindungen</a> Molekularverbindungen. Im Gegensatz zu den Alkalimetallen kann Wasserstoff ein Elektron von Metallen aufnehmen und bildet mit ihnen salzartige <a href="/wiki/Hydride" title="Hydride">Hydride</a>. Die wichtigste charakteristische Eigenschaft des Wasserstoffatoms ist die Fähigkeit, das einzige Elektron an das Molekül Wasser unter Bildung des <a href="/wiki/Oxonium" title="Oxonium">Hydroniumkations</a> zu verlieren. Dieses Kation spielt bei allen chemischen Reaktionen in wässrigen Lösungen eine wichtige Rolle. Die genannten Besonderheiten des Elements Wasserstoff, haben dazu geführt, dass man in Lehrbüchern auch die Auffassung findet „Wasserstoff gehört im Periodensystem zu keiner bestimmten Gruppe“.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>Jedoch gibt es auch chemische Eigenschaften und chemisches Verhalten, in denen Wasserstoff den Alkalimetallen ähnlich ist. Wasserstoff ist wie die Alkalimetalle ein starkes <a href="/wiki/Reduktionsmittel" title="Reduktionsmittel">Reduktionsmittel</a> und tritt wie die Alkalimetalle stets einwertig auf. Wasserstoff wandelt sich unter extrem hohem Druck in eine metallische Hochdruckmodifikation um, den <a href="/wiki/Metallischer_Wasserstoff" title="Metallischer Wasserstoff">metallischen Wasserstoff</a>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Umgekehrt haben auch einige Alkalimetalle unter bestimmten Bedingungen Eigenschaften wie Wasserstoff, z. B. besteht Lithium als Gas zu 1 % aus zweiatomigen Molekülen. </p> <div class="mw-heading mw-heading2"><h2 id="Literatur">Literatur</h2></div> <ul><li>A.
