<P> The d - block is on the middle of the periodic table and includes elements from columns 3 through 12 . These elements are also known as the transition metals because they show a transitivity in their properties i.e. they show a trend in their properties in simple incomplete d orbitals . Transition basically means d orbital lies between s and p orbitals and shows a transition from properties of s to p . </P>
