WebTheir properties are transitional between highly reactive metallic elements of s−block which are typically ionic compounds and elements of p−block which are large - covalent. The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number … WebTransition elements are defined as elements with partly filled d orbitals (or those that easily create them). The d-block components in groups 3–11 are transition elements The f-block elements, also known as inner transition elements (lanthanides and actinides), also satisfy this condition due to the fact that the d orbital is partly filled prior to the f orbitals.
