For a chemist the two basic tools of a chemist are these two subjects, which are used as an aid for understanding any type of chemistry, so in my perception, if these are taught in foundation courses individually instead of relating to a branch of Chemistry, students will have better chance and more clear concepts especially with the advanced research tahts why I asked the question

If you want to teach chemistry in a deductive manner (which can be done at a higher level only) you start with atomic structure - quantum numbers - periodic table (which can be actually deduced from atomic structure). Once you get to periodic table you can naturally go over to ionization potential, electron affinity, electronegativity. Plotting the sum and difference of electronegativity of atomic pairs you easily get the well known triangle of ionic, covalent and metallic bonding with all intermediates. I beleve that this relatively simple way intergates quite naturally the basic disciplines of atomic structure, peridic table and bonding. For a more precise descripion you must go to quantum chemistry, but that is a quantitative rather than qualitative explanation. Do you agree with this scheme?
