Platinum group

The platinum group or platinum family is a group of six metal elements with similar physical and chemical properties. The family consists of ruthenium, rhodium, palladium, osmium, iridium, and platinum. These transition metals occupy the rectangular area in the periodic table at the intersection of periodic table groups, 8, 9, and 10 with periods 5 and 6.

Strictly taken the elements of Period 4 (iron, cobalt and nickel) have lots of similar physical (high density and melting points) and chemical properties (e.g. catalysts and complex compounds) as well so it is unclear why these elements do not belong to this Platinum group.
