Answer:
+
6
Explanation:
This is the dichromate ion,
C
r
2
O
2
−
7
.
Oxygen is more electronegative than chromium, so it'll take its usual
−
2
charge here. There are seven oxygen atoms, so the total charge is
−
2
⋅
7
=
−
14
.
Let
x
be the oxidation number of two chromium atoms. So, we got:
x
+
(
−
14
)
=
−
2
x
−
14
=
−
2
x
=
12
So, two chromium atoms have a total oxidation number of
+
12
. Since one is not more electronegative than the other, we can divide the number by two to get one chromium's oxidation number.
12
2
=
6
So, a chromium atom here has an oxidation number of
+
6
.
HOPE THIS HELP YOU..☺️☺️

⭐Hola User...!!!
_______________
⭐Here is YOUR Answer..!!!!
〽________________
↪Oxidation states....
↪BAsically the total charge on the complex ion is -2 ...
↪thus also ww know that. . oxygen has -2 oxidation state..
↪so here applying formula we get as ....
↪lets the oxidation of Cr ( chromium ) be X
↪so
↪2X + 7 (-2) = -2
=》 2X -14 = -2
↪=》 2X = -2 +14
=》 2X = 12
↪THUS X = +6
↪< THUS the oxidation state of Cr is +6 >
