Question

Write an equation that shows the formation of a chromium(ii) ion from a neutral chromium atom.

Answer 1

Answer : The balanced equation will be,

`Cr\rightarrow Cr^(2+)+2e^-`

Explanation :

Oxidation : It is the process of losing of one or more electrons.

Reduction : It is the process of gaining of one or more electrons.

The balanced equation will be,

`Cr\rightarrow Cr^(2+)+2e^-`

A neutral chromium atom is oxidized into chromium(II) ions by the loss of two electrons.

Answer 2

The equation that shows the formation of chromium (ii) ion from neutral chromium atom is as follow
Cr ---> cr^2+ + 2e-
Cr^2+ is the chromium ion with oxidation state of two which is one of the common ion of chromium. Other common ion of chromium include chromium of oxidation state 6 and 3
