The range of the of the oxidation number of the first transition series is +2 to +6.

What is transition metal?

Transition elements or transition metals are elements or metals that have partially filled d orbitals.

Examples of first transition metals

The first main transition series begins with either;

  • scandium (Sc, atomic number 21)
  • titanium (Ti, atomic number 22)
  • chromium (Cr, atomic number 24) and ends with
  • zinc (Zn, atomic number 30)

Range of oxidation number of transition metals

  • scandium -  oxidation number = +3
  • titanium - oxidation number = +2, +3, and +4
  • Chromium - oxidation number = + 6
  • zinc - oxidation number = +2

Thus, the range of the of the oxidation number of the first transition series is +2 to +6.
