La has atomic number 57.Ac has atomic number 89.They both are first elements of lanthanoids and actinoids group respectively.
Actinium (Ac) is a chemical element with the atomic number 89, located in the actinide series of the periodic table. It is a radioactive metal that is primarily used in research and some specialized industrial applications.
The eighty ninth element in the periodic table is Actinium, with the symbol Ac and atomic number 89. It is a radioactive element that is part of the actinide series.
The lanthanides and actinides are located in the f-block of the periodic table. The lanthanides are found in the sixth period, spanning from cerium (Ce, atomic number 58) to lutetium (Lu, atomic number 71). The actinides are in the seventh period, ranging from actinium (Ac, atomic number 89) to lawrencium (Lr, atomic number 103). Both series are typically displayed separately at the bottom of the periodic table to maintain its overall structure.
Actinoids family contain: Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lw.
The correct members of group 3 of the periodic table are Scandium (Sc), Yttrium (Y), Lutetium (Lu), and Lawrencium (Lr). Actinium (Ac) is not a member of group 3, while Lanthanum (La) is part of the lanthanide series and not considered a member of group 3.

The elements are called Actinides. They are placed at the bottom of periodic table. These elements have different properties.These elements are in the f group of the periodic table. Elements from Ac-Lr belong to this group. These are called Actinides.
The radioactive element in period 5 of the periodic table is Actinium (Ac). It is a radioactive metal with atomic number 89.
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.
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.
