The elements which are present between s and p-block elements in the modern periodic table are called transition elements. Chemistry. The S-, P-, D-, And F-block Elements. In transition elements, the last electron enters penultimate d orbitals i.e. As the atomic number increases the total number of electrons increases along with the addition of shells. Oxidation States. Most of them form covalent compounds. Save. Physical Properties of d-block elements:-1.Atomic Radii:-Sc—->Decrease—–>Cr—->ConstantIncrease—>Zn Atomic radii decrease as we move from left to right, but in the mid way atomic radii become constant. Every spinning electron in an atom or molecule can behave like a tiny magnet. These elements constitute one of the two series of inner transition elements or f-block. F-block elements are the elements on the periodic table between atomic numbers 57-70 and 89-102. These elements constitute one of the two series of inner transition elements or f-block. Understanding the d and f block Elements. These elements are called transition elements as they show transitional properties between s and p-block elements. Based on this they are differentiated in lanthanides and actinides. The f-block elements are also known as inner transition elements, although that term is normally taken to include lawrencium and lutetium as well, which are part of the d-block elements. This contrasts with the considerable similarities in properties of the elements of the s-block and also between those of the d-block. 15:00 mins. d and f Block Elements - Groups 3 to 12 elements are called d-block elements or transition elements.
