Question

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

Answer 1

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

Answer 2

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.
