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.
