My questions deals with elements, their positions on the periodic table and how strong or weak acids are. Is there a trend between the position of elements on the periodic table and how acidic they are when bonded with Hydrogen. For example, when discussing acids, H-F is considered a weak acid but H-I is a very strong acid with H-Br and H-Cl being in between the two. So does this mean that acids become stronger the lower the element involved in the bond is on the periodic table?
Fluorine is very electronegative so it won't easily give up its electrons which is what a strong acid would do easily. The disassociation energy trend is that that it decreases going to the left and up which can tell you if a certain acid is stronger than another. The lower the disassociation energy the weaker the acid. If you notice Hydrogen and Fluorine both have small radii so the disassociation is small and the radii of Hydrogen and Iodine together is bigger than those of HF so the disassociation energy if higher.
