<b>groepen</b> ingedeeld worden, op basis van een bepaald aantal <a href="/wiki/Scheikunde" title="Scheikunde">chemische</a> kenmerken die zij gemeen hebben. Een groep is dus niet meer dan een verzamelnaam voor een aantal elementen. De meeste van deze groepen vallen samen met de kolommen van het systeem. De <a href="/wiki/Platinagroep" title="Platinagroep">platinagroep</a> beslaat meerdere kolommen en de (horizontaal weergegeven) <a href="/wiki/Lanthanide" title="Lanthanide">lanthaniden</a> en <a href="/wiki/Actinide" title="Actinide">actiniden</a> worden meestal tot de <a href="/wiki/Scandiumgroep" title="Scandiumgroep">scandiumgroep</a> gerekend. De grootste groep, de <a href="/wiki/Overgangsmetaal" title="Overgangsmetaal">overgangsmetalen</a>, kan worden onderverdeeld in een aantal subgroepen. </p><p>Veel groepen zijn genoemd naar de naam van het eerste element in de groep, zoals bij de <a href="/wiki/Boorgroep" title="Boorgroep">boorgroep</a>. Andere groepen hebben vaak om historische redenen een aparte naam, zoals de <a href="/wiki/Edelgas" title="Edelgas">edelgassen</a>. Er zijn ook groepen die tegenwoordig een andere – meer systematische – naam hebben dan vroeger, zoals de <a href="/wiki/Stikstofgroep" title="Stikstofgroep">stikstofgroep</a> die voorheen als <i>pnicogeen</i> door het leven ging. </p> <table style="background:none; color:inherit; font-size:85%; padding:0; border-collapse:collapse; text-align:center" border="0" class="vatop"> <tbody><tr
