A) chromium (Z = 24)
B) manganese (Z = 25)
C) iron (Z = 26)
D) titanium (Z = 22)
Correct Answer: B
Solution :
Manganese shows maximum number of oxidation states because it has S unpaired electrons in 3d and also contains 2 electrons in 4s-subshell. + 2, + 3, + 4, + 5, + 6, + 7 Other metals show the following oxidation states Cr = + 2, + 3, + 4, + 5, + 6 Fe = + 2, + 3 Ti = +2, + 3, + 4You need to login to perform this action.
