(1) Rare earth metals are a group of 17 elements: europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium, lanthanum, cerium, praseodymium, neodymium,
promethium, and samarium.
Rare earths are 17 chemical elements in the periodic table, specifically 15 lanthanides: lanthanum, cerium, praseodymium, neodymium,
promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, as well as scandium and yttrium.
Promethium Pm 61 nuclear powered battery (current 5-year life span), portable X-ray machines, heat source to provide auxiliary power for space probes and satellites, lasers for communications with submarines.
