Lanthanum (La) and actinium (Ac) are two chemical elements, solid metals.
Lanthanum and lutetium: lantanides group Actinium and lawrentium: actinides group
Lanthanum and Actinium
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!
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.
Actinium is a silvery-white, metallic element that is soft and malleable. It readily reacts with oxygen and moisture in the air, forming a dull oxide layer on its surface. Due to its radioactivity, actinium glows faintly blue in the dark.
After the IUPAC nomenclature lanthanum is a lanthanoid and actinium is an actinoid.
Lanthanum and actinium have different properties. So, they are kept apart from the periodic table.

Lanthanum and Actinium
Chemically, actinium is similar to lanthanum. Actinium react with halogens (F, Cl, Br, I), oxygen, sulphur, etc.
Lanthanum and lutetium are members of the lanthanoids family.Actinium and lawrencium are members of the actinoids family.

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.
After the new IUPAC nomenclature: yes.
Elements La(Lanthanum)-Lu(Lutetium) are the lanthanides. Elements Ac(Actinium)-Lr(Lawrencium) are the actinides.
Actinium is a silvery-white, metallic element that is soft and malleable. It readily reacts with oxygen and moisture in the air, forming a dull oxide layer on its surface. Due to its radioactivity, actinium glows faintly blue in the dark.
