Syllabus dot point 5A states "Process information from secondary sources to describe recent discoveries of elements"

My question is.. how recent is 'recent'??

 

[Pwnage101]

past 20 years is fine

check out Darmstadtium, Hassium, etc...

 

[gurusson]

anything that hasn't been given a name yet. i.e still follows nomenclature rules e.g. ununhexium is prob safe

 

[jackc91]

Has anybody come across any q's that directly address this dotpoint?

 

[Fortify]

Has anybody come across any q's that directly address this dotpoint?

Yes, in Dot Point.

"Describe recent discoveries of elements."

"Identify two recently discovered elements and outline their method of production." Eg: ununpentium, hassium, meiterium

I don't think I've ever seen it in exams. But maybe it has popped up somewhere.

 

[Timothy.Siu]

its just the transuranic elements like after some number, maybe 88 or something

yeah, that seems right, my teacher last year made us look at an element made in 1999

 

[jet]

Yeah. We did 112, 116, 118 etc. They were all discovered very recently. There are two labs – one at Berkeley and one in Russia.

 

[undalay]

Anything within the past 50 years is reasonable.

 

[Ishynooshy]

Element 112 discovered a few days ago in Darmstadt.
