Lewis Structure of SO3

Answer 1

S has 6 valence electrons

0 has 6 valence electrons: total 18 for 3 Oxygen

O(formal charge): 6(valence electrons)-4(Non bonding Valence Electrons)-4(bonding electrons)/2=0

ormal charge): 6(valence electrons)-0(N0nbonding Valence Electrons)-12(bonding electrons)/2=0

The molecular geometry of SO3 is trigonal planar

Type of Hybrid orbita:SP2

Angle between bonded atoms: 120o

Answer 2

Sulfur would be the central atom. 3 oxygens branch out. 2 of the oxygens have single bonds; 1 oxygen has a double bond. total of 24 electrons used. The central sulfur has a formal charge of +2, while the two oxygens which are single bonded to the sulfur each have formal charges of -1.

[This answer is wrong. Sulfur is the central atom and the three oxygen do branch from it, but each oxygen is double bonded to the sulfur. Your formal charge calculations were correct but you did not fully minimize it. The reason sulfur can be an "octet rule violator" in this case (having 12 electrons being shared) is because it is in the third period and has access to what are called d sub-shell energy levels].

The first answer is correct, but in reality the sulfur is bonded by the strength of 4/3 of a bond. The Lewis structure is denoted by three bracketed drawing, showing a double bond with each oxygen separately.

Answer 4

It's trigonal planar, and it exhibits resonance.

SO3's simplified Lewis structure looks something like this:
