What is the first actinide element?
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.
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.
What family does Curium belong to on the periodic table?
Curium belongs to the actinide family on the periodic table. Actinides are located in the f-block of the periodic table and are known for their radioactive properties. Curium is a synthetic element and is named after the scientist Marie Curie.
What family does californium belong in?
California belongs to the actinide family, which is the 15-element series with atomic numbers 89 to 103 on the periodic table. These elements are known for their radioactive properties and include heavy elements such as uranium, thorium, and plutonium.
What is the first element of the actinides?
The first element in the actinide series is actinium , a chemical element in the periodic table that has the symbol Ac and atomic number 89.The actinide (or actinoid) series encompasses the 15 chemical elements that lie between actinium and lawrencium on the periodic table , with atomic numbers 89-103.The actinides get their name from the first element in the series , actinium.

What is americium element family?
Americium belongs to the actinide element family, which is a group of radioactive elements found in the actinide series of the periodic table. Actinides are characterized by their high atomic numbers and radioactivity. Members of this family include uranium, plutonium, and thorium.

What is a actinide?
Any of a series of chemically similar, radioactive elements with atomic numbers ranging from 89 (actinium) through 103 (lawrencium). they are outer transition elements All of these elements are radioactive, and two of the elements, uranium and plutonium, are used to generate nuclear energy
Where are the actinides placed in the periodic table?
The actinide series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. There are two rows below the periodic table, the first row is lanthanides and the second row is actinides.
What family does californium belong in?

Where is the Actinide series located on the periodic table?
The second row of the bottom 2 rows under the periodic table. (Period 7, starting at Group 4)
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).
