Answer:
Explanation:
Sulfur has valence electron 6 and oxygen has 6*3 = 18 valence electrons. In this drawing, you'll see that sulfur violates the octet rule that is it has more than 8 electrons but it is legal since sulfur is in 3rd period, and elements that fall in 3rd period or more in periodic table can use their d orbitals and others to go beyond the normal "8" electrons in valence shell rule which is octet rule
All the formal charges are minimized...that is everything has formal charge of 0 in this structure which is always encouraged.
Credits to chemistNATE who wonderfully explains it in his video.
