Lanthanide chemistry is dominated by the +3 oxidation state and as such they bear a superfical resemblance to group 13. Lanthanide 3+ ions are larger than those of group 13. Group 13 elemnents Ga, In, Tl also form compounds wher the metal oxidation number is +1. Lanthanides on the other hand can form compunds with formal oxidation number of +2, (in particular Eu) , and +4 (in particular Ce).

What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
What are the elements of 4F series called?
The 4f series is referred to as the Lanthanides.
What are the groups below the main group elements on the periodic table called?
3d-block elements or tranformation elements and 4f-block elements or lanthanides and actinides
Elements in the d block are also known as?
These elements are called "main group elements".
Are there are more nonmetallic elements than metallic elements?
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
What are the elements between 57 and 70 called?
Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
What are the elements of 4F series called?
The 4f series is referred to as the Lanthanides.
What transition elements are called lanthanides and acttinides?
Elements La(Lanthanum)-Lu(Lutetium) are the lanthanides. Elements Ac(Actinium)-Lr(Lawrencium) are the actinides.
How do 3a differ from other group of elements?
The group 3 of the periodic table include lanthanides and actinides.
Synthetic elements are found in what group?
The Actinoids group contain all the synthetic elements. All the elements that have an atomic weight of 95 and above do not occur naturally. They are part of the actinoid elemental group.
Elements in the first row of the rare elements of the periodic?
the lanthanides
What are the groups below the main group elements on the periodic table called?
3d-block elements or tranformation elements and 4f-block elements or lanthanides and actinides
What are the elements 57 71 called?
Lanthanides
Elements in the d block are also known as?
These elements are called "main group elements".
Elements with atomic numbers of 58 through 71 are known as the?
The elements beginning with Lanthanum (atomic number 57) and ending with Lutetium (atomic number 71) are called Lanthanides. They are also known as rare earth elements.
Are there are more nonmetallic elements than metallic elements?
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
