I NEED HELP PLEASE, THANKS! :)

Draw the Lewis structure for sulfur trioxide, SO3.

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.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

that's what i got you can count the number of atoms
