SO2 Lewis structure - Learnool
WebThe total number of bonding electrons around the boron is 8 (full octet). One-half of this is 4. Now let’s see the lewis structure of SO2. In SO2, the sulfur’s valence electron = 6 And the valence electrons of oxygen = 6 There are 2 oxygen atoms in the compound, thus = 6*2 = 12 So, total valence electrons = 18 Sulfur is in group 6 (Chalcogens) of the periodic table with the electronic configuration [Ne] 3s²3p⁴. Therefore, the Sulfur atom contributes 6 x 1 = 6 valence electrons. Oxygen has six valence electrons (group 6) and has a valency of -2. Oxygen’s electronic configuration is 1s22s22p4. Meer weergeven To form the Lewis structure of Sulfur Dioxide, we need first to determine the number of valence electrons available. These … Meer weergeven Now that we’ve calculated the number of valence electrons available to us, we move on towards building up the Lewis structure for SO2.
