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.
The atomic number of the element lanthanum on the periodic table is 57.
No, uranium is a metallic element. It is a heavy, silvery-white metal that belongs to the actinide series of the periodic table.
Lanthanides are any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57 - 71). With scandium and yttrium, they make up the rare earth metals. Their atoms have similar configurations and similar physical and chemical behaviour; the most common valences are 3 and 4.
Lanthanum is a metal. It is a transition metal that belongs to the lanthanide series in the periodic table.
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
Uranium is an actinoid series element.
Lanthanum is a natural element.
The element Lanthanum (La) is a transition metal and the first of the 'Lanthanides'.

The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
The atomic number of the element lanthanum on the periodic table is 57.
A disintegration series is the pathway of a radioactively unstable element into a stable element. The pathway alters the atomic number of the element and converts the element into another element. A common one is the uranium disintegration series.
After the IUPAC nomenclature lanthanum is a lanthanoid and actinium is an actinoid.
