I feel dead tired, just came home around 9.30. Today we learnt about Atoms in a much more deeper concept which is totally O.O to me. Shells and sub-shells are still fine by me since its still related to the electronic configuration that we learned in Secondary level but ORBITAL is totally a new concept that I need to grasp fast. If I'm not wrong this is what Mr.Tan said, "Orbital is the region whereby it is possible to indicate where the electrons are most likely to be found." Maybe he wrote that or said it, doesn't matter and Orbital can be divided in to s, p, d, and f.

Just printed my own set of notes and reading ahead and found more familiar stuff coming back to haunt us during our 3 years in M.I. Stuffs like bonding, but looking at the my thick notes, we're going in depth regarding the topic bonding. Something about Ionisation and determining/caculating the shape of a molecules scares the living crap out of me. Ok off to sleep.
