The attraction between two atoms involved in metallic bond is increased with the increase of electrons in d-orbitals. Most transition metals are grayish or white (like iron or silver), but gold and copper have colors not seen in any other element on the periodic table. The largest block of elements in the periodic table is a group known as the transition metals.These metals are found in groups three through twelve of the periodic table (the so-called d-block elements), although there are ongoing differences of opinion about exactly which elements should be classed as transition metals and which should not. The most abundant transition metal in Earth's solid crust is iron, which is fourth among all elements and second (to aluminum) among metals in crustal abundance. A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals.On the basis of this definition, scandium and zinc do not count as transition metals - even though they are members of the d block.. Scandium has the electronic structure [Ar] 3d 1 4s 2.When it forms ions, it always loses the 3 outer electrons and ends up with an argon structure. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated. The transition metals are also known as thetransition elements or the d-block elements. name of cation (charge in Roman numerals) + name of anion.
