How many lanthanides and actinides are there?
There are 15 lanthanides (atomic numbers 57-71) and there are 15 actinides (atomic numbers 89-103)
What are the properties of lanthanides and actinides?
The lanthanides and actinides are part of the inner transition metals. Actinides are all radioactive, highly electropositive and tarnish readily in air. Lanthanides burn easily in air, have high melting and boiling points and are strong reducing agents.
What group in the periodic table has more than one column?
All groups except the lanthanoids and the actinoids.
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
What are the properties of 'f ' block elements?
they are of two types lanthanides and actinides
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
How reactive are lanthanides and actinides metals?
lanthanides and actinides are fairly reactive, but not as much as say, the alkali metals in group 1
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
Why are lanthanides in period six and actinides in period 7?
Lanthanides have 6 electron shells. Actinides have 7 electron shells.

What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
What group in the periodic table has more than one column?
All groups except the lanthanoids and the actinoids.
How do 3a differ from other group of elements?
The group 3 of the periodic table include lanthanides and actinides.
Are group 12 on the periodic table lanthandies or actinides?
No. There are two rows at the bottom of the periodic table. the first row elements are called lanthanides and the second row elements are called actinides.
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
