1. What did you guys get for the last question?
2. I got 1200, 0.120, 8.5x10^-4 or x10^-3, 66.44 for the calculations that i can remember and i wrote hourglass shape! Dumbell and figure 8 didnt cross my mind at the time!
3. what did you guys put for the 'lowest first ionisation energy, lowest fourth ionisation energy and lowest boiling point'??

Sodium silicon and neon
5. NONONONO

Na
Si - not sure if correct
Na - lowest ionisationenergy = lowest boiling point
Neon not sodium!

Na

I think I put flourine because metallic bonding in Na may be? But I may have put Na

wasn't the molecules or something equal to 5.117 x 10^20?? then divided by avo constant??
I dont remember the exact value, 2 looks like a 5 in my memory i guess, but if thats the value then thats what i used, i do remember the magnitude tho.

sodium silicon and neon
yas yas yas i wrote the same

What was the last cross and dot diagram ?

I swapped the numbers to charges on the opposite ion and then balanced it out.

Na
Si - not sure if correct
Na - lowest ionisationenergy = lowest boiling point
I put Ne for lowest boiling >.< because simple bonding structure. I don't know anymore

i think you then times that answer by 2 as it is in N2 moecule, explains the two marks
13. No... It is neon

Sorry but i got it wrong! Nirtogen has a greater atomic radius->weaker van der waals so lower boiling point, my mistake
no need to apologise , oh well! hopefully that's the only one mark you've lost

Yup got those answers, what was the question where 8.5x10^-4 was the answer, i forgot

Haha no i was right the first time, its neon -.-

I got 1.7 x10 to the power of -3 for the amount of nitrogen one???
Yesss, did you times the value by two
19. Was the reaction disproportionation?
