- Email toby.hudson@sydney.edu.au for questions on the course
- Email Robert.baker@sydney.edu.au for problems with labs
- Email firstyear@chem.usyd.edu.au for questions on chemistry admin
- Go to first year chemistry learning centre (back of lab D) for extra help with
course work – tutors available MON-THURS 1-2pm
History of chemistry
o Metallurgy- Bronze Age, Iron Age
o Four elements: earth, water, air and fire
o Middle ages mostly concerned with transforming
stuff (alchemy)
o Antoine Lavoisier- chemistry as a science relied on
him. He relied on quantitative, reproducible
experiments
o John Dalton (atomic theory)- theory that all matter
consists of atoms, that atoms of one element cannot
be converted into atoms of another and that atoms
of an element are identical and are different from
atoms of any other element is wrong
Matter
Pure substances can be further divided into
elements (e.g. copper) or compounds (few
elements combined together- same chemical
elements in each molecule e.g. 1 brown 2
blue)
Elements in nature
o Oly 6 our orally as atos: He, Ne, Ar, Kr, Xe, ‘ Nole or Inert
Gases
