Transuranic element?? (1 Viewer)

[ballerinabarbie]

omg i have no idea what a transuranic element was - let alone how it was produced!! hopefully that question will be marked 2 marks for the radioisotope and 2 marks for the transuranic element...
oh and the transuranic element in multi choice? chromium or caesium? or something else??

answer

Uranium has the highest atomic number of naturally occuring elements: 92. Elements with a higher than A.N 92 can be artificially made from neutron bombardment and high speed positive bombardment, these are transuranic elements. And for the multi choice, you just had to find the element with a higher than 92 atomic number, its curium

i put down curium

 

[crazylilmonkee]

ditto..
i had no idea
crapped on bout cyclotrons and stuff
dunno it was correct
m/c i think it was d

 

[tegs]

I know, i bullshitted about cyclotrons and reactors and got it all wrong I think. Oh well.
I put curium too, yay!!!

 

[Ragerunner]

They reactors/cyclotron is right

They bombard elements to make them neutron-rich and as a result will decay.

Well I talked about the reactors and particle accelerators and bombarding the atom with neutrons even though I really had only a vague idea about this lol so hopefully I will get some marks!

 

[Ragerunner]

I put some equations to make it look good

 

[Misturi]

i put down curium too.

hmm... i think i put positive because neutron wouldn't work for my eqiations, even though i thought it was right

same

yeah.. it's probably one mark for examples/equations for each.

for the neutron bombardment it cant be too high of a speed otherwise it just smashes the atom (a la physics course) it needs to be slow moving so it absorbs it, then its Neutronroton ratio will be outside the zone of stability and undergo beta decay which raises atomic number by 1

examples for both tranuranic and commercial?

 

[Exeter]

example i just did, if u do neutron bombardment on a u-238 u get this

(238 92)U + (1 0)n --> (239 92)U --> (239 93)Np + (0 -1)e

[i think its neptunium, cant relally remember]

for commercial i talked about technitium99m and americium 241
