Question

6.a)Find the oxidation state of Mn in MnCl2 and MnO2

(oxidation state of Cl : -1 O: -2 . Atomic no of Mn: 25)

b)Write the subshell electronic configuration of Mn ion in MnO2

c)d block elements shows variable oxidation state . Why?​

Answer 1

1. Mn Oxidation state in MnCl2 = +2 and MnO2 = +4
2. little confuse about it
3. d block elements shows vaiable oxidation cause of these reasons

• available of lack d orbitals
• higher value of fai
• they are small in size so higher E.N
