i just hope the little v sign means neutrino

yeh, but they had a v dash, which means anti-neutrino

 

[seadonkey]

Yeah..my last one was 1.666 x 10^-27 im pretty sure

the first one also sounds familiar

1.666 x10^-27 is right

 

[seadonkey]

yeh, but they had a v dash, which means anti-neutrino

beta decay u do get anti neutrino. it was orignally called the neutrino but research showed it hav anti matter propeties. so it was renamed the anti-neutrino

 

[zahid]

I wrote a whole booklet 8 pages for the 7 marker...i didn't want to loose any marks.

 

[B.J]

same here, cept i rounded it off to 3 sig fig

yeh i got 234 Pa aswell

Really? Pa? how does that happen i thought it would lose a number..... i got 234 Ac

 

[rithvikt]

can sum1 xplain 31b the decaying shit....i got the thorium mass number but wtf is that Q nuclide...?..beats me

 

[mrkotter]

use the data sheet to know if the maths is right for the mass dilation of the proton. Yeah it doesnt help with doing the mass but at least you know if your getting the right answers.

Its a beta decay so atomic number goes up one and mass stays the same. This gives Pa-234 (from memory)

 

[richz]

actually Pa-234, becuz the th particle from the first reaction undergoes beta decay. so Th-234 undergoes beta decay

 

[rithvikt]

lol..whoops...i knew it was undergoing beta decay..but i thought Q was an actual particle so i was looking it up in the periodic table..

 

[thunderdax]

Who said Q wasn't a particle?
Edit: Oh right, I get you now. Unlucky, all of us do stuff like that occasionally

 

[hall of mirrors]

What did you guys get for that pauli contribution question...

 

[richz]

lol..whoops...i knew it was undergoing beta decay..but i thought Q was an actual particle so i was looking it up in the periodic table..

lmao, ur funny

 

[richz]

What did you guys get for that pauli contribution question...

umm... he discovered the neutrino??? its a dotpt??

 

[hall of mirrors]

you didnt mention his exclusion principle?

 

[Captain Gh3y]

you didnt mention his exclusion principle?

The exclusion principle is not really necessary to explain what Pauli contributed to beta decay, (the neutrino is the main thing).

Although now that I think about it, the neutrino idea originally arose from exclusion principle. That's because exclusion principle showed that it is not possible for an electron to exist inside the nucleus, therefore the beta particle is not originally an electron within the nucleus, but is created when a down quark turns into an up quark, and... etc.

 

[richz]

lol, captain, no need to go to deeply, it was only worth 3 marks

 

[rama_v]

Yeah
No need to explain the exclusion principle fo rthat question. Just had to say that he came up with the neutrino to explain the anomalous energy distribution of beta particles during beta radiation

 

[debaser]

easy option, easy test full stop. yay the hsc is over and im still drunk 27 hours later.

 

[Bizarre]

did u get 1.70 *10^-27 kg

and rest mass was 1.67*10^-27 kg

both 3 sig figs

The ress mass of the proton was within that 1.6 - 1.7 x 10^-23 kilograms.

Want to know the easiest way to check?

Data sheet. "Mass of Proton"

And I talked about the exclusion principle explaining why the electron was ejected during beta decay, rather than joining th atom.

Also, it was Pa. Uranium is 92. Subtract 2 protons, is Thorium - element 90. Plus one proton (beta decay) is element 91 - Proactinium.
