Detailed explanation with examples on f-block-actinoids-general-characteristics-and-applications-of-d-and-f-block-elements helps you to understand easily , designed as per NCERT. Their compounds are generally coloured. The elements which are present between s and p-block elements in the modern periodic table are called transition elements.Transition elements have partly filled (n-1) d-orbitals. • Because of stronger interatomic bonding, transi Transition element is defined as the one which has incompletely filled d orbitals in its ground state or in any one of its oxidation states. These elements are also called as inner transition elements because they form a transition series within the transition elements. D-Block Elements. The concept videos are presented by an expert with deep knowledge of the subject. On moving down the group metallic character increases. The period number represents the principal quantum number of the valence shell of the elements present in it. The term appears to have been first used by Charles Janet.

An element block is a set of elements located in adjacent element groups. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. The fourth 6d-series which begins with Ac is still incomplete. The periodic table is divided into four blocks of elements called s-, p-, d-, and f- blocks. F block elements are divided into two series, namely lanthanoids and actinoids. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
