Lanthanides is a series of the fifteen metallic-chemical elements in the group 3 of the periodic table. From Lanthanum-Lutetium.. All of the Lanthanides atomic numbers from 57-71 are (La) Lanthanum, (Ce) Cerium, (Pr) Praseodymium, (Nd) Neodymium, (Pm) Promethium, (Sm) Samarium, (Eu) Europium, (Gd) Gadolinium, (Tb) Terbium, (Dy) Dysprosium, (Ho) Holmium, (Er) Erbium, (Tm) Thulium, (Yb) Ytterbium and (Lu) Lutetium. Practically in other words all of metallic chemical elements that ends with IUM are the ones that belong to Lanthanides. An example for Samarium is the optical glass of the picture because it has the samarium element that makes peoples vision better not only on the glass but on the measure of vision it needs to have.

Samarium goes with the topic because it has Lanthanides since Lanthanides consists of the metallic element. Samarium is one the Periodic Table Lanthanides group, being the penultimate row of the periodic table. There are 9 rows on the periodic table if you count them, so the lanthanides are on the penultimate row (the 8th row).
