Ok since I took chemistry back in middle school, I'll tell you #1: Lanthanum and Actinium are the beginning elements of the Actinide and Lanthanide series, that's why the series is named after them #2: They are chemically arranged differently (Ex:The # of protons and neutrons and electrons) #3 If they were in the series, why would the series be named after them? Hope this helped!
What else can I help you with?
Why F-block are called lanthanides and actinides?
they termed as lanthanide because the lighter elements in series are chemically similar to lanthanum
Where do the lanthanides and actinides get their names?
The lanthanides get their name from the element lanthanum, which was the first in the series to be discovered. The actinides get their name from actinium, which was the first element in this series to be discovered.
Which really belong to group iii - lanthanum and actinium or lutetium and lawrencium?
Lanthanum and lutetium: lantanides group Actinium and lawrentium: actinides group
What is actinium classified as?
Actinuim is a member of the family of 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.
What transition elements are called lanthanides and acttinides?
Elements La(Lanthanum)-Lu(Lutetium) are the lanthanides. Elements Ac(Actinium)-Lr(Lawrencium) are the actinides.
Why F-block are called lanthanides and actinides?
they termed as lanthanide because the lighter elements in series are chemically similar to lanthanum
How many lanthanides and actinides are there?
There are 15 lanthanides (from lanthanum to lutetium) and 15 actinides (from actinium to lawrencium) in the periodic table. These elements belong to the f-block of the periodic table and have unique properties due to their electron configurations.
Where do the lanthanides and actinides get their names?
The lanthanides get their name from the element lanthanum, which was the first in the series to be discovered. The actinides get their name from actinium, which was the first element in this series to be discovered.
Which really belong to group iii - lanthanum and actinium or lutetium and lawrencium?
Lanthanum and lutetium: lantanides group Actinium and lawrentium: actinides group
What is actinium classified as?
Actinuim is a member of the family of actinides.
What is actinium classified under?
Actinuim is a member of the family of actinides. Actinium is a solid metal, radioactive with the atomic number 89.
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.
What is lanthanum and actinium?
Lanthanum (La) and actinium (Ac) are two chemical elements, solid metals.
Lanthanum does not belong to lanthanide series actinium does not belong to anthanide series why?
After the IUPAC nomenclature lanthanum is a lanthanoid and actinium is an actinoid.
What are the lanthanum and actinium series set apart from the periodic table?
Lanthanum and actinium have different properties. So, they are kept apart from the periodic table.
What has the author K W Bagnall written?
K. W. Bagnall has written: 'Lanthanides and actinides' -- subject(s): Actinide elements, Rare earth metals 'Chemistry of the rare radioelements: polonium-actinium' -- subject(s): Actinium, Polonium, Radiochemistry
