letra de lanthanide metals song periodic table - kids learning tube

[chorus]
we are the lanthanoids, or the rare earth metals
fifty-seven to seventy-one on the periodic table!

[verse 1]
i’m lanthanum, my symbol is “la”
my atomic number’s fifty-seven and atomic mass is one-thirty-eight
i’m mostly used to make carbon arc lights, don’t you know?
which are used for studio lighting for a motion picture show
h-llo there, i am cerium! my symbol is “ce”
my atomic number’s fifty-eight, my atomic mass is one-forty
i am used in motion picture arc lighting as well
i’m also used in flints for lighters, now isn’t that swell!
i’m praseodymium, my symbol is “pr”
my atomic number’s fifty-nine, one-forty’s my atomic mass by far
my primary use is as an alloying agent
i make high strength metals used in aircraft engines
i’m neodymium, my symbol is “nd”
my atomic mass is one-forty-four, my atomic number is sixty
i’m used when making goggles for glass blowers and welders
and i’m used in some glass to make spectrometers
my atomic number’s sixty-one, i am promethium
my atomic mass is one-forty-five, and my symbol is “pm”
i could be used to make a nuclear battery
with a lifespan of five years, that is satisfactory!
[chorus]
we are the lanthanoids, or the rare earth metals
fifty-seven to seventy-one on the periodic table!

[verse 2]
my atomic number’s sixty-two, i am samarium
my atomic mass is one-fifty, my symbol is “sm”!
i am also used in motion picture arc lighting
i make flints in lighters, now isn’t that exciting!
my atomic number’s sixty-three, i’m europium
my symbol is “eu”, my atomic mass is one-fifty-one!
the most reactive of the rare earth metals, you know?
and i’m a good absorber of neutrons, as scientists show
“gd” is my symbol, i am gadolinium
my atomic number’s sixty-four, my atomic mass is one-fifty-seven
i’m the greatest element known to capture thermal neutrons
and in nuclear reactors i’m used as control rods
hi, i’m terbium! my atomic mass is one-fifty-eight
my atomic number’s sixty-five, “tb”‘s my symbol, isn’t that great!
i was discovered in a quarry in a town called ytterby
in a country of sweden, in 1843!
dysprosium’s my name, my atomic number’s sixty-six
my symbol’s “dy”, one-sixty-two’s my atomic mass, mixed
i absorb neutrons and my melting point is high
i’m used in nuclear reactor’s control rods so they don’t fry
i’m holmium, my symbol is “ho”
atomic number’s sixty-seven, my atomic mass is one-sixty-four
i’m used in magnets for my magnetic properties
my name comes from the latin word “holm”, as you can plainly see!
my symbol is “er”, i am erbium
atomic number’s sixty-eight, atomic mass is one-sixty-seven
i’m used as a doping agent in fiber optic cables
i am used in the nuclear power industry when able
my atomic number’s sixty-nine i am thulium
my atomic mass is one-six-eight, and my symbol is “tm”
the least abundant of the naturally occurring rare earth metals
i’ve been used to create lasers, i have one isotope that’s stable
i’m ytterbium, my atomic mass is one-seventy-three!
my symbol’s “yb”, my atomic number’s seventy
i have one isotope that may be used
as a radiation source in a portable x-ray if approved
my symbol is “lu”, i am lutetium
atomic mass is one-seventy-four, my atomic number’s seventy-one
lutetium’s one of the most difficult elements to prepare
and has little commercial use because i am so rare!
[chorus]
we are the lanthanoids, or the rare earth metals
fifty-seven to seventy-one on the periodic table!
