Question

What is the oxidation number of Cs in Cs2O

Answer 1

Oxidation number of Cs in
`Cs_2O` is +1

Step-by-step explanation:

Oxidation number is defined as a number assigned to a element which represents the number of electron lost or gained by the element.

There are some general rules for assigning oxidation number:

Elements in their elemental state assigned oxidation 0.

Sum of oxidation number of all the atoms in a neutral compound is zero.

Oxidation number of oxygen in a compound is usually -2.

In peroxides, oxidation number of oxygen is -1.

If oxygen is bonded to fluorine, then its oxidation number is +1

Calculation of oxidation no. of Cs in
`Cs_2O`

The given compound is neutral and not peroxides.

Therefore oxidation no. of oxygen in
`Cs_2O` is -2.

Let the oxidation no. of Cs be x

2 (x) -2 = 0

x = 2/2

= +1

Oxidation number of Cs in
`Cs_2O` is +1

Answer 2

The oxidation number of Cs in Cs2O would be +1. The oxidation state, often called the oxidation number, is an indicator of the degree of oxidation (loss of electrons) of an atom in a chemical compound. Hope this answers the question. Have a nice day.
