Inner transition elements
The 'f' block elements are called inner transition elements. There are two series of 'f' block elements. These are the '4f' and '5f' series called Lanthanides and Actinides. The general ou..
f - block Elements
The f - block elements are also called as inner transition elements. As the last electron enters the f-orbital these elements are called as f - block elements. These are divided into two se..

d and f - block Elements
The elements that lie in between S-block and P-block are the d-block elements. These elements are called transition elements as they show transitional properties between s and p-block elem..
Transition elements
'd' block elements are called transition elements. These elements occupy groups 3 to 12 on the periodic table. There are four series of transitional elements, '3d', '4d', '5d' and '6d' depending on the energy levels of 'd' orbit..
The 'f' Block Elements
The 'f' block elements are those, which in their elemental or ionic forms have partially filled 'f' orbitals. The differentiating (last) electron enters 'f' orbitals, which lie inner to the second outermost (penultimate) shell. ..
..Predicting Period, Group and Block of an Element
Knowing the electronic configuration, one can predict the period, which corresponds to the principal quantum number of the valence shell. The block of the element corresponds to the sub shell, which receives the last electron. The position of an element in the long fo..
Transition Elements
All the elements belonging to 3 to 12 groups are called transition elements. They resemble each other in several physical and chemical properties. They are all metals. They are called transition elements because they are placed between the most rea..
The s- Block Elements
Introduction - The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This ..
