Well, I've decided to keep chem (not that I had much choice)
But I figure as I'm doing it, I might aswell put in some effort ... And that may mean a lot seeing as I got <20% on the Unit 1 exam
Though I need help. My question here is, which prior knowledge from Unit 1 is needed for Unit 2, and more importantly for Unit 3/4... And which of that knowledge is not needed at all....
I need to know so I can get busy these holidays firstly trying to catch up, then trying to get ahead
I have copied the list of what is needed for Unit 1 (now I need to know what we actually need to know for Units 2/3/4 or what would help)
Unit 1 CHEMISTRY
The Periodic Table
historical development from Mendeleev to Seaborg
trends and patterns of properties within The Periodic Table: atomic number, types of compounds
formed, metallic/non-metallic character, chemical reactivity of elements;
atomic theory
historical development of the model of atomic theory with contributions from Dalton to
Chadwick
limitations of the model of atomic theory
mass number, isotopes, calculation of relative atomic mass, electronic confi guration including
subshells;
the mole concept including empirical and molecular formulas, percentage composition, Avogadros
constant;
interpretation of data from mass spectrometry.
models of bonding to explain observed properties including melting temperature, electrical
conductivity, chemical reactivity, shape, polarity of bonds, intermolecular forces
metals
ionic compounds
molecular substances, network lattices, layer lattices;
limitations of the bonding models;
properties and systematic naming of alkanes and alkenes up to C6;
structural isomers of C4H10;
behaviour of surfaces and the application of surface chemistry in nanotechnology;
addition polymers
relationship between structure, properties and applications,
synthesis, cross-linking
development of customised polymers.
