Properties of D and F block elements ; The F-block Elements or Inner Transition Elements
The F-block elements are a group of elements in the periodic table that are located in the inner transition elements. This group includes the elements from lanthanum to lutetium.
The F-block elements are unique in that they have partially filled d orbitals. This means that they can easily form compounds with other elements. Additionally, these elements are very good at absorbing radiation.
Classification of F – Block Elements
F- block elements are those elements found in Group III of the periodic table. This group includes the elements scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), and nickel (Ni).
F- block elements are all metals. They are shiny, silver-white in color, and are good conductors of electricity. They are also relatively strong and durable. They are found in nature as ores, which are minerals that contain large amounts of a particular element.
What are Transition Elements?
Transition elements are elements that are located in the d-block of the periodic table. They are elements that have partially filled d-orbitals. This means that they can form more than one type of ion. Transition elements have a variety of properties that make them useful in industry.
Properties of Transition Elements
The transition elements are a group of elements in the periodic table that include the lanthanides and the actinides. They are called transition elements because they are located in the d-block, which is the block of elements that lie between the s-block and the p-block.
The transition elements are all metals, and they have a number of interesting properties that make them useful in a variety of applications. First, they are all relatively abundant, and they are all relatively easy to extract from the ground. They also have a variety of different colors, which makes them useful in a variety of decorative applications.
Most importantly, the transition elements have a number of unique properties that make them useful in a variety of technological applications. They are all good conductors of electricity, they are all good magnets, and they have a variety of different useful oxidation states. This makes them ideal for use in a variety of electrical and magnetic applications.
Transition Elements List

The Lanthanoids
The Lanthanoids are a group of six metallic elements in the periodic table. They are located in the lower left hand corner of the table and are represented by the letter L.
The Lanthanoids are:
Lanthanum (La)
Cerium (Ce)
Praseodymium (Pr)
Neodymium (Nd)
Promethium (Pm)
Samarium (Sm)
Lanthanum is the first element in the Lanthanoids. It is a soft, silvery-white metal that is found in the earth’s crust. It is used to make light bulbs and camera lenses.
Cerium is the second element in the Lanthanoids. It is a soft, silver-white metal that is found in the earth’s crust. It is used to make light bulbs and camera lenses.
Praseodymium is the third element in the Lanthanoids. It is a soft, silvery-white metal that is found in the earth’s crust. It is used to make light bulbs and camera lenses.
Neodymium is the fourth element in the Lanthanoids. It is a soft, silvery-white metal that is found in the earth’s crust. It is used to make light bulbs and camera lenses.
Promethium is the fifth element in the Lanthanoids. It is
Properties of Lanthanoids
The lanthanoids are a group of 15 closely related elements in the periodic table. They have some similar chemical and physical properties, but also some unique ones.
The lanthanoids are all relatively soft metals. They are all poor conductors of electricity, and they all have a low melting point. They also have a low boiling point, and they are all soluble in water.
The lanthanoids all have a similar electron configuration. They all have a valence electron in the 4f orbital. This gives them all a similar chemical reactivity.
The lanthanoids all have a very similar physical appearance. They are all silvery-white metals that are relatively soft.
The lanthanoids are all very rare elements. They are all found in trace amounts in the Earth’s crust.
The Actinoids
The actinoids are the six elements in the periodic table that are located in the bottom right hand corner of the table. They are all radioactive elements that have very short half lives.
Properties of Actinoids
The actinoids are a group of elements that share a number of physical and chemical properties.
They are all shiny, silvery metals.
They all have a high melting point and are good thermal and electrical conductors.
They are all relatively reactive and corrode easily in moist air.
They all form a range of coloured compounds when reacted with other elements.
Neptunium: An Important Element of the Actinoid Series
Neptunium is a heavy and radioactive element that is part of the actinoid series on the periodic table. It is not found naturally on Earth, but is created in nuclear reactors. Neptunium has a number of important applications, including in nuclear weapons and energy production.
