Webfirst step in drawing a Lewis structure is to calculate the total number of valence electrons in the molecule. Hydrogen is in Group 1 of the periodic table and therefore, has 1 valence electron. Bromine is in Group 17 of the periodic table and therefore has 7 valence electrons. We add those together: 1 + 7 = 8 total valence electrons.
