Lanthanum - Periodic Table of Videos

[Mishuntertatgenhorst]

What was the rhyme again? Does anyone know when Lanthanum was added to the periodic table.

[Debbie321lopez]

Holmium (Ho) and Erbium (Er), makes Hoer (whore)  in Dutch, and that how a teacher at my school lets students know the rare earth elements.

Languid centers play notes promises small European golden tongues dinosaurs huckalapede thrumming yellow lutes???

[vmelkon]

Lanthanum, the slightly radioactive element.

[FordPrefect23]

Lanthanum is also used in camera lenses, many older soviet lenses make use of it and they are excellent lenses.

This seems more memorable

@Demonlogist Chuck Norris sends you a round-house kick.

[catsfromhell1]

@BigTex541 No.

That mnemonic is so random it's barely easier than just remembering the list of elements! :-)

Why are scandium and yttrium considered as rare earths?

[BirdValiant]

From Wikipedia: "Scandium and yttrium are considered rare earths since they tend to occur in the same ore deposits as the lanthanoids and share similar chemical properties with them."

[KyuubiNaruto1337XD]

no they aren't they just are put into the same group because they have the same properties as each other, and because they have the same number of valence electrons

[champagnerocker]

Lanthanum has no f electrons. I was always taught that it is a d-1 transition metal, not a lanthanide, and should always be below scandium & yttrium in the table.

[Hellothere212121]

You con cut sodium with a knife as well.

[tomandjj]

yeh but that's to be expected of an alkali metal this is a transition metal making it far more amazing that it can be cut with a knife.

[tomandjj]

sorry it's a rare earth metal not a transition metal. however, if the rare eath metals hadn't been first discovered when they were then they would be classified transition metals anyway.

[Craydon]

Yes. Oddly most elements are metals...

[HHOhybridBuilder]

Is lanthanum a kind of metal?

[robotwarsfan03]

dunno went too fast

[cleocatra]

What's that rhyme he said?

[GamblerJustice]

Language centers praise Ned's promise of small European garden tubs dinosaurs hobble erotically thrumming yellow lutes.

[cleocatra]

Haha! Thanks!
