Class PeriodicTable

java.lang.Object

org.openscience.cdk.tools.periodictable.PeriodicTable

public final class PeriodicTable
extends Object

Represents elements of the Periodic Table. This utility class was previously useful when one wants generic properties of elements such as atomic number, VdW radius etc. The new approach to this is to use the Elements enumeration.
