I've noticed that the past papers haven't seemed to have a 6 marker on the properties of the noble gases and how they relate to their uses so it might be worth taking extra time to revise that topic. I'm not really sure about other topics though.

yeah
maybe not then, but graphite did come up in 2012 and again in 2014, so I don't think we should rule it out completely

it is possible that it will come up but not as a 6 mark

i think the 6 marks will be rates of reaction and reactivity of alkali metals down the group due to structure or with water

Method for making and isolating salt using base.
Method for making and isolating salt using alkali
Compare/contrast conductivity of graphite, ionic cpds and metals
Compare mpt. and bpt of named compounds/elements wrt bonding and structures
Discuss bonding and structure in named cpds. Or elements.

Ionic bonding
covalent bonding
metallic bonding

coloured compounds (transition metals)
halogens/halides
alkalis
noble gases and uses

how to draw dot cross diagrams
properties of ionic, metallic, giant and simple covalent bonding

using the periodic table to find elements and using groups and periods
diamond and graphite
all the 6 formulas you need to know; relative formula mass, relative atomic mass, empirical formula, reacting masses, percentage composition and percentage yield. if you don't know how to do them, youtube have plenty of videos if you search; quantitive chemistry additional science.


hope this helps.

E.g.1

Suggest method for making CuSO4 from CuO and H2SO4. How would you isolate salt formed?

E.g.2
Suggest method for making NaCl from NaOH and HCl. How would you isolate salt formed?
