EPA (1998-03-02). 2 - NaCl is said to dissociate in water. Now, to determine the formal charge of H, we will simply subtract 1 from the valence electron of H predicted by the periodic table. [68][needs update], In 2006, a study reported a statistical association between environmental levels of perchlorate and changes in thyroid hormones of women with low iodine.
