Question

metal M forms peroxide of type Mo2 valency of the metal with respect to oxygen

Answer 1

Hello friend !!!

Here's the answer you are looking for

The valency of M with respect to oxygen is +4.

Since the valency of O is -2 always , by Criss cross method the compound becomes M2O4 which is same as MO2.

Answer 2

The valency of the metal M, with respect to oxygen, is +4.

• Any element's bonding ability in the given compound is indicated by its valency.
• It is the number of electrons that an atom must receive or lose in order to achieve the electrical configuration of a noble gas.

Given:

Metal M form peroxide $MO_{2}$

To find:

Valency of M with respect to oxygen

Solution:

According to the question, the metal peroxide $MO_{2}$ consists of one metal atom and two oxygen atoms.

$M + O_{2}$→  $MO_{2}$

Each oxygen atom carries a −2 charge.

So, total charge on oxygen= 2 (-2)= -4

To create a neutral molecule, the positive charge on the M atom must balance the negative charge on the oxygen (O) atom.

Let the valency of the metal M= x

So, x+ (-4)= 0

or, x= +4

Therefore, the valency of the metal with respect to oxygen is +4.
