getFormula

public abstract String getFormula()

getMassDefect

public abstract double getMassDefect()

The amount by which the mass of all atomic nuclei in this composition differs from the sum of the masses of its constituent protons, neutrons and electrons. This is the mass equivalent of the energy released in the formation of the nucleus.

Returns:

the mass defect
