recent disco of elements (1 Viewer)

[lilkatie]

I hate how nuclear chem is randomly stuck in pom.
Anyways
Describe recent discoveries of elements?
Hmm should I pick a newly disc element or what, or how they discover them

 

[Sirius Black]

Any transuranic element with atomic number>100 will be ok

I chose to do element 118 coz u hav so much to talk about it.

 

[lilkatie]

Ununoctium sounds good tah
so what do they mean by describe it
um it's a superheavy element
mass number 293, 118 protons and 175 neutrons in its nucleus
is that enough of a description?

 

[Sirius Black]

hmm, I think that's not enough- at least u need to mention the process of making this element briefly: element 118 and its immediate decay product 116 were discoverd by accelerating a beam of krypton-86 ions into an energy of 449 million electron volts and directing the beam into targets of lead-208

 

[lilkatie]

great! thankyou

you can also talk about hassium, its hte fusion of 2 elements, firing Fe Nuclei at a Pb target, (this is going off my memory, i could be wrong)

Hi

I STRONGLY advise students from terming Z=118 an element.

It is HIGHLY recommended that students choose elements 109, 110 or 111, which have all been offically named and recognised by IUPAC.

All the information you will need can be found at:
www.WEBELEMENTS.com
and just click on your the element you want to study.

I think element 109 should be studied by all, why? cause it was named after one of the greatest chemists of the 20th century, but one that recieved little credit for her work, in her time.
Who? go to http://www.sdsc.edu/ScienceWomen/meitner.html


Best of luck

Hi

I STRONGLY advise students from terming Z=118 an element.

Why couldn't we term it as an element. I have noticed the fact that Berkerly retracted their discovery on element 118 coz they were unable to reproduce their initial result but does that mean 118 does not exist as an element?

 

[funking_you]

If the 'element' pertaining to Z=118 (likewise 116) has not been created, can you really call it an element in the 'real' sense of the word.
I'm must exits before you can classify it as an element, so what does it mean 'to exist', well in chemistry, if it is matter, it exist.

We had Ununoctium as our religion in year 10. Good times.

hmm i'm sure element 118 would be fine, as long as you can say some stuff about it so they know you're not just making up some random number
