Manganese is encountered
as its oxide, manganese(IV) oxide which catalyses the decomposition
of hydrogen peroxide and the purple ion manganate(VII). Its
principal oxidation states are +2 and +7, but+4, +5 and +6 states
are also known.

Group numbering and the modern periodic
table
The
original group numbers of the periodic table ran from group 1
alkali metals to group 0 noble gases. To account for the d block
elements and their 'vertical' similarities, in the modern
periodic table, groups 3 to group 0 are numbered 13 to 18. So, the p block elements are
referred to as groups 13 to group 18 at a higher academic level,
though the group 3 to 0 notation is still
used, but usually at a lower academic level. The 3d block
elements (Sc to Zn) are now considered the head (top) elements
of groups 3 to 12.
