For H2SO4 we have a total of 32 valence electrons. The O bonded to H has SN = 4 (two bonding pairs and two lone pairs). This compound is also known as Sulfuric Acid. One reason can also be stated here to define the strength of the bonds because as we know oxygen is highly electronegative to the hydrogen causing the molecules to be held tightly. What is this device for? Also, iodine is in the seventh group of the periodic table and has seven valence electrons in its outer orbit. This is the reason why electrons are closer to these two elements instead of hydrogen. Required fields are marked *.
