Periodic Table
	Introduction This periodic table can be accessed from several other programs, whenever input of a mass is required. It shows all elements with their isotopes, relative abundances and atomic masses. It takes only a few clicks to determine the most abundant Nd isotopes or the exact mass of 28SiH.
	Step 1 - Choose Element Click on any element to select it.
	Step 2 - Choose Isotope After an element is selected, its isotopes are displayed at the top of the window. The natural abundances of the isotopes are also displayed, both in digital form and on a logarithmic scale. By default, the most abundant isotope is always pre-selected (40Ca in this case). To choose a different isotope, just click on it.
	Mass Display for Single Ions After step 2, the exact mass (in amu) of the selected isotope is displayed here.
	Select This Monoatomic Ion The text on this button updates with your selections. If all you want to do is to choose a monoatomic ion, you just click here to exit the periodic table. That will take to where you came from and the name and/or the exact mass of this ion will be automatically entered in the respective places. But wait, there is more...
	Build a Molecule To build a molecule with the the currently selected ion, click here. It will be added to the list of molecule components. Repeat steps 1 and 2 and then come back to this button to add to your molecule.
	Select This Molecule The text on this button changes while you build your molecule. Right now, a 12C14N molecule is selected. If you are happy with your creation, click this button. That will again take you to where you came from and the name and/or the exact mass of this molecule will be automatically entered in the respective places.
	Mass Display for Molecules The exact mass (in amu) of the molecule you built is displayed here.
	Clear the Molecule Clicking this button will clear the list of molecule components. You always get another chance.
	Cancel This button takes you out of the periodic table without selecting anything. It will take you back to where you came from, but without changing anything there.
