The Lanthanides are a Period of Elements in the sixth period.
They all metals. They all have variable oxidation states, but oxudation state '3' is the most stable.
They lie in the Periodic Table between Group (II) (Alkaline Earth metals) and the Transition Metals.
What else can I help you with?
In what type of orbitals are the actinide and lanthanide electron found?
Actinide and lanthanide electrons are typically found in f-orbitals. These orbitals are part of the inner electron shells and have a distinctive shape compared to the s and p orbitals.
Is uranium a lanthanum series element?
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
Where is the actinide series found?
Actinide series are in period 7, starts after Actinium(89) next with atom numbers 90 till 103, in group 3'A': the 5f suborbital is 'fiiled up' with 0-14 electrons. Uranium (92) is the most known and the last natural occurring ('stable' isotope mass 238) element.
Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
What was Seaborg's last major change to the Periodic Table?
Seaborg's last major change to the Periodic Table was the actinide concept. He proposed placing the actinide series below the lanthanide series to create the extended table and highlight the similarities between the two series.
What are the series of inner transitions elements and what is a trait of each?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
What are the two series of inner transition elements and what is the trait of each?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
What are the two metal groups?
the two groups of metals is the Lanthanide series and the Actinide series.
The lanthanied actinide series make up the inner transition metals true or false?
True. The lanthanide and actinide series make up the inner transition metals. The lanthanide series includes elements with atomic numbers 57-71 (lanthanides), while the actinide series includes elements with atomic numbers 89-103 (actinides).
What is the name of two series of inner Transition elements?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
Is Magnesium a metal from the lanthanide series or actinide series?
Neither. Magnesium is an alkaline earth metal (group II).
Is americium a lanthanide?
No. Americium is an actinide.
Plutonium is a type of lanthanide or actinide or regular transition element?

Is uranium a lanthanum series element?
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
Are lanthanide and actinide elements in groups 13-16?
no !
Is californium a lanthanide or a actinide?
Californium is a member of the actinoids family.
