In what way are the electronic structures for lanthanides and actinides similar?
Lanthanoids and actinoids both have a + 3 most common oxidation state.
The f-orbitals gradually fill in both series.
In both series, the ionic radius of the whether decreases as the number increases.
For all the cases, the electronegativity in both series is low..
What are the analytical applications of lanthanides and actinides?
Actinides are all radioactive elements.
Lanthanides are used in optical devices (night vision goggles), petroleum refining, and alloys.
Actinides are found primarily in applications where their radioactivity can be used to power devices such as cardiac pacemakers..
What is the electronic configuration of lanthanides and actinides?
Therefore, the electronic configuration of Lanthanides is Xe 4 f 1 - 14 5 d 0 - 1 6 s 2 and the Actinides is [ Rn ] 5 f 0 - 14 6 d 0 - 2 7 s 2 ..
What is the extraction method of actinides?
A method for separation of actinide elements comprising feeding a solution containing actinide elements such as americium, curium, californium and the like, into a resin column in which a weakly basic primary, secondary or tertiary anion exchange resin obtained by resinifying pyridine, imidazole or alkylamine has been .
Where are the lanthanide and actinide series found?
Lanthanides and actinides are in periods 6 and 7, respectively.
Generally, they are placed underneath the periodic table.
The lanthanides are between Barium and Hafnium.
The actinides are between Radium and Rutherfordium..
Why is the chemistry of actinoids much more complicated than that of lanthanoids?
The chemistry of the early actinoids is more complicated than the corresponding lanthanoids , due to the large number of oxidation states possible for these actinoids and their radioactive nature..
Why lanthanides and actinides are kept separately in the modern periodic table?
Lanthanides and Actinides are placed in separate rows at the bottom of the periodic table because they are too wide and occupy lots of space.
So to conserve space, Lanthanides and Actinides are placed down the periodic table..

- Lanthanoids and actinoids both have a + 3 most common oxidation state.
The f-orbitals gradually fill in both series.
In both series, the ionic radius of the whether decreases as the number increases.
For all the cases, the electronegativity in both series is low. - With a few exceptions, lanthanides are non-radioactive elements.
The primary distinction between actinides and lanthanides is that actinides may quickly form complexes, whereas lanthanides cannot.
Actinides are more radioactive, and lanthanides are not.
