8.13 The oxidation states displayed by the first half of the first row of transition metals are given in the table below.

METALS	Sc ( [Ar] 3d¹4s²)	Ti ( [Ar] 3d²4s²)	V ( [Ar] 3d³4s² )	Cr ( [Ar] 3d⁵4s¹)	Mn ( [Ar] 3d⁵4s²)
OXIDATION STATES		+2	+2	+2	+2
	+3	+3	+3	+3	+3
		+4	+4	+4	+4
			+5	+5	+6
				+6	+7

Except for Sc, all others metals display +2 oxidation state. This is because as the atomic number increases, the number of electrons in the valence shell increases. +2 oxidation s
