Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
Sulphur
Sulphur fracture refers to the irregular, porous appearance of a mineral fracture caused by the brittle nature of sulphur. When sulphur is broken or fractured, it typically exhibits a rough, uneven surface with jagged edges. This fracture pattern is a characteristic feature used to identify sulphur in its natural state.
Sulphur is solid at 20 Celsius.
Copper is a metal because it is a good conductor of electricity and heat, and it has a shiny metallic luster. Sulphur is a non-metal because it is brittle, does not conduct electricity, and tends to form negative ions in chemical reactions.
At room temperature, it is in gaseous state. When it evolves it is red in colour and smells like burning sulphur.
Sulfur has a Mohs density of 2; it is soft.
When sulfur is heated, it undergoes a phase change from solid to liquid, and then from liquid to gas due to sublimation. Sulphur does not undergo a direct change from solid to gas.
Iron sulphide is an ionic compound. The Iron is in a +2 oxidation state and the sulphur is in a -2 oxidation state.

Hydrogen Sulphide contains the element Hydrogen in a +1 oxidation state and the Element Sulphur in a -2 oxidation state. It is a covalent moelcular molecule with single bonds between each hydrogen and the central sulphur. The sulphur has two lone pair of electrons. The structure is a vee formation.
Yes. Sulphur is homogeneous.
