Boiling point isn't something you calculate, it is a property of each element. The periodic table sometimes lists this property in the box for the element.

a covalent bond is formed when two or more elements SHARE ELECTRONS to form substance. an example would be H2O. an ionic bond is when two or more elements TRANSFER ELECTRONS to form a substance. an example would be NaCl why are ionic bonds so strong, and ionically bonded structures melt and boil at extremely high temperatures? this is because the ionic bonds holding them together are very strong. why do covalently bonded substances have a much lower melting and boiling point? this is because, for a covalent compound to melt or boil, you only need to break a force called the van der waals force. this is a very weak force which exists between the ions. yeah that's all i can help with. btw, i live in singapore, and the terms i use may be different with the terms you use, so you must try to make sense, and substitute the terms you use in.

You need to get a reference to the boiling points - try seeking out a good periodic table program. I use Kalzium - http://edu.kde.org/kalzium/
