n 1: a white soft metallic element that tarnishes readily;
occurs in rare earth minerals and is usually classified as
a rare earth [syn: lanthanum, La, atomic number 57] |
atomic number 58
(wn) | atomic number 58
n 1: a ductile grey metallic element of the lanthanide series;
used in lighter flints; the most abundant of the rare-earth
group [syn: cerium, Ce, atomic number 58] |
atomic number 59
(wn) | atomic number 59
n 1: a soft yellowish-white trivalent metallic element of the
rare earth group; can be recovered from bastnasite or
monazite by an ion-exchange process [syn: praseodymium,
Pr, atomic number 59] |
