public class SingleElectron
extends ElectronContainer
implements Serializable, ISingleElectron, Cloneable

A Single Electron is an orbital which is occupied by only one electron. A radical in CDK is represented by an AtomContainer that contains an Atom and a SingleElectron type ElectronContainer:

   AtomContainer radical = new AtomContainer();
   Atom carbon = new Atom("C");
   carbon.setImplicitHydrogens(3);
   radical.addElectronContainer(new SingleElectron(carbon));
