I'll take a look at this: Cas Liber (talk · contribs) 09:07, 10 July 2016 (UTC)

Usually found in combination with cerium.. - any extra meaning gained by saying it like this and not, "Usually with cerium..." ?

Yeah, this was confused and confusedly combined with the second sentence. Changed to "Lanthanum usually occurs together with cerium and the other rare earth elements." Double sharp (talk) 09:20, 10 July 2016 (UTC)

lanthanum makes up over a quarter of the lanthanide content. - huh? Is this right?

Hmm, this is from the monazite article (24%), so it should be "around". Changed. Double sharp (talk) 09:20, 10 July 2016 (UTC)

I screwed up - thought of lanthanide as compound of lanthanum rather than rare earth metal :P Cas Liber (talk · contribs) 12:34, 10 July 2016 (UTC)

complex multistage extraction process - are both the first two words needed?

Well, it would be a little trivial to say it's extracted using an extraction process. I think the point of the sentence is the complexity, which is why pure La wasn't produced for almost a century after its discovery. Shortened it to read "It is extracted from these minerals using a multistep process of such complexity that pure lanthanum metal was not isolated until 1923."

I meant using one word or other instead of removing both, but like alternative. Cas Liber (talk · contribs) 12:35, 10 July 2016 (UTC)

OK; removed "multistep", as the latter seems more important to me here. Double sharp (talk) 14:45, 10 July 2016 (UTC)

anywhere to link subshells to? or the various electrons...4f etc....

Linked to Electron shell#Subshells. 4f, 5d, and 6s are also explained there, so I'm not sure if we should link them again to the same place. Double sharp (talk) 14:45, 10 July 2016 (UTC)

link binary compounds

I'd spell out Sc2O3 and Y2O3 in words with formulae in brackets
