The Lewis Dot Structure for sulfur dibromide (SBr2) can be drawn as follows: Steps to Draw the Lewis Dot Structure for SBr2 ( i)Count the total number of valence electrons. Sulfur (S) has 6 valence electrons. Bromine (Br) has 7 valence electrons, but there are two Bromine atoms, so multiply by 2. Total valence electrons = 6 + (7*2) = 20 electrons. (ii)Draw the skeleton structure of the molecule. Sulfur is the central atom, and the two Bromine atoms are bonded to it. (iii)Distribute the...
