Question

What is the oxidation number of Oxygen in RbO2?​

Answer 1

Answer:

oxidation number of oxygen = -1/2

Explanation:

this is a super oxide .It's name is rubidium peroxide.

let x be the oxidation number of oxygen.

then from algebraic rule

+1+2x =0

so, x=-1/2

Answer 2

The Oxidation number of Oxygen in RbO2 is +1​

RbO2 is  superoxide known as Rubidium oxide.

Explanation:

• A superoxide is  having two oxygen atoms
• One oxygen will have one negative charge.
• Oxygen atom requires an electron to fill its valence shell
• Thus oxidation state is +1.
• Rubidium oxide is highly reactive towards water,
• It is bright yellow colour.
• It is prepared by elemental Rubidium and Oxygen.
