[Review Topics] [References Many elements combine with hydrogen(valence 1) to give compounds called hydrides. Use the position of an element in the periodic table to deduce its valence. Write formulas for these hydrides without using subscripts, for example XH3. If no hydride forms, write "none". What is the fomula of the hydride formed by arsenic?
