Which from following statements is true for group 16 elements?

Options

  1. AAll elements of this group form EO ₂ type oxides
  2. BIt includes all the nonmetals
  3. COxides of all elements of this group are gaseous at room temperature
  4. DReducing properties of dioxides of this group element decreases form SO ₂ to TeO ₂

Correct answer

D. Reducing properties of dioxides of this group element decreases form SO ₂ to TeO ₂

Step-by-step solution

Besides EO ₂ type, Sulphur, Selenium, and tellurium also form EO ₃ type oxides. Group 16 Elements: Oxygen and Sulfur are non-metals, Selenium and Tellurium are metalloids and Polonium is a metal under typical conditions. All the elements of this group need 2 electrons to attain inert gas configuration either by gaining or sharing of electrons. Oxygen has high E.N so it gains two electrons to become inert gas configuration so all metal oxides are ionic and contains O ²⁻ in which the oxidation state is -2 . Oxygen sh
