How was your chemitry paper?

[Svet !]

i have seen in my encyclopedia that it should be 13p and 14 n like the normal aluminium so u got it write do not worry

i hope so the paper was quite easy but i made so many silly mistakes and now im so scared , did you choose the last question on organic ?

 

[ahmadumar]

I'm really confused about the isotope thingy, I put 13 and 14 but my friends are saying it's 13 and 13 or 13 and 15. I'm so scared. Does somebody have a certain answer? T_T

your luck
u wrote the correct answer

 

[ahmadumar]

14 nuetron is CORRECT , while no cmnts for 13 or 15 Nuetron ..they might be , or might not be ...

no!
other than 14 neutrons all are wrong man

 

[ahmadumar]

well i wasnot sure of other than 14 ...so I said it ..
but according to the Statement it Said " ONE NATURALLY OCCURING " so it means that it is 14 Nuetron Isotope ...
other wise Radio Active Isotope of Aluminium is also there , which is NOT naturally occuring

yeah you're right

But wiki says that there are TWO naturally occurring isotopes, the stable one (Al-27) AND the radioactive one(Al-26) :l However it also says that Al-27 is more naturally abundant (99.9+ %)

this is what the wiki says!
didnt you read what the question said!?

What did it say?

 

[ahmadumar]

What did it say?

Aluminium has only 1 naturally occuring isotope.
write the neutrons & protons of this isotope. ​

 

[Miss_Z]

Exactly dude.

If Al-27 is the answer (according to what wiki says), then No. of protons is 13 and No. of neutrons is 14.

yeah exactly!
A;-27 is the answer.

Yeah exactly!
ab bs yahi kr sakte hain ke P4 acha kr lein

p4 ke liye toum kis tarein ki tarari karte ho?

isotope has diffrnt number of neutrons so 14 neutrons is normal it had to be either 15 or 13...unfotunately 14 is wrong.in the periodic table at the back of the paper we had 14 nuetrons alumium so we had to write 15 or 13

when it says that an element has only one isotope its the element itself for example gold has only one isotope gold it self!!!

past papers krta hn

 

[ahmadumar]

yyeah adeel is right man!

Refer to previous arguments.

so how was the ATP today guys ?
