Found it easy, alhamdulillah!:biggrin:
A lot of people found it easy so I guess the grade boundaries might be high!:colonhash:

honestly, it was good. some of the MCQs were a bit rubbish (what was that A = B +/- C +/- D question???) but overall ok. section B was as good as past papers. but a lot of people think the same thing so GB might be really high :frown:

what was ur lattice enthalpy value? was it like a positive number and something like 2,000 something??
and why did phosphorus have a less/or more ionization energy than sukphur?? and what about aluminium one too??

if someone did normal, but messed up in unit 1, can he/she get a good grade by performing really good in unit 2??

Hey!My lattice energy was smth around - 2000.. because there is a slight repulsion between the 2 electrons in the 3px orbital..And about aluminum, I wrote that the outer electron (in 3p sub shell) is shielded by inner 3s electrons -> first i.e. is lower in aluminum.

If you're aiming for an A, you can get an A if you got a high B in U1 and get a good A in U2

Damn really?! that was for 3 marks right?
I found this paper the most easiest compared to all the previous ones.
