Sulfur has 16 protons, 16 neutrons and 16 electrons. Its atomic number is 16, and it has an atomic mass of 32.066 amu. Sulfur is a pale, yellow, non-metallic...
S can form up to 6 bonds with oxygen in the compound SO3. That is, three double bonds. Look up expansion of the valency octet. The S atom has 12 electrons in its outer level in SO3. because sulfur is larger than oxygen, it does have the ability to expand its valence shell and form more than two bonds. In other words, the Octet Rule only really works for the smaller atoms, and is easily violated on larger ones. For example, in H2SO4, the sulfur atoms is bonded to 4 O atoms.
