Frequently Asked Questions on F Block Elements
What are Inner Transition Elements?
Inner transition elements, also known as f-block elements, are a group of elements found in the two bottom rows of the periodic table (lanthanides and actinides). They have partially filled f-orbitals.
Why F-Block Elements are Called Inner Transition Elements?
F-block elements are called Inner Transition elements because they involve the filling of innermost F-orbitals during electron configuration.
Write name of Five F-Block Elements.
Five f-block elements are:
- Lutetium (Lu)
- Hafnium (Hf)
- Uranium (U)
- Neptunium (Np)
- Curium (Cm)
What is General Electronic Configuration of F-Block Elements?
The general electronic configuration of f-block elements is [noble gas] 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f1-14 5s2 5p6 5d10 5f1-14 6s2 6p2. The f-orbitals are being filled.
What is key Difference Between Lanthanide and Actinide?
The key difference between lanthanides and actinides is their placement on the periodic table. Lanthanides are in the f-block from atomic number 57-71, while actinides are from 89-103.
What is Lanthanoid Contraction?
Lanthanoid contraction is the decrease in atomic and ionic radii of elements in the lanthanide series, caused by poor shielding of the increasing nuclear charge as electrons fill the 4f orbitals.
Are all F Block Elements Radioactive?
No, not all F-block elements are radioactive. Some, like lanthanides and actinides, have radioactive isotopes, but not all of them are inherently radioactive.
F Block Elements
F-Block Elements in Chemistry, also known as Inner Transition Elements, comprise a group of elements located in the two rows at the bottom of the periodic table. Elements with filled f orbitals are found within this section. The f-block is positioned in the sixth and seventh periods of the periodic table, with the sixth period referred to as the lanthanide series and the seventh as the actinide series.
In this article, we will discuss the topic of F-Block Elements, including their properties, position in the periodic table, electronic configurations, as well as their real-world applications.
