Just for the ease of memorising all the stupid definitions and formulae etc. Xueyin

For the stuff that Yuan Han posts: "A very important thing to note that I only wish to provide a more comprehensive and/or simplified understanding of the concepts. I do not use proper terms at times and the correctness in my posted materials are subject to my own limited understanding and knowledge. Therefore, the reader is warned not to copy the things inside here for Chemistry tutorials/tests/exams. I will not be held responsible for bad grades/wrong answers resulting from use of my posted material." Thanks Yuan Han

First chem-note-beyond-alvl. 4 quantum numbers of electrons in an atom. By Yuan Han note warning above

2nd chem-notes-beyond-alvl Revision of Lewis structure, VSEPR, and Atomic orbitals By Yuan Han note warning above

Notes on hybridization (ignore those involving d orbitals), basic molecular orbital theory and resonance if you're interested. By Jeremy Koo

By Yuan Han note warning above

By Yuan Han note warning above

The scanned version of the VSEPR thing, the shapes of molecules. It might slightly unclear. Note that N2O is N (triple bond) N (dative bond) O Note that in dot-and-cross diagram, you must shade the dot, i.e. cannot be a circle. Note that in most cases, the positive/negative charge is on the central atom ICl4 (-), exceptions being CO3 (2-), NO3 (-) and some other bigger anions. Note that in ALL cases, the charge of the ion should not be indicated on the atom, but indicated as the overall charge, even if there are many atoms, i.e. [CO3] 2-
