Summary notes of Transition Metals and their compounds

[Brief GCE A level H2 Chemistry tuition notes by Mr Chong, chemistry tutor]

Part One (Part Two is also found on the sidebar)


The notes found on this post are grossly inadequate for 2019 and beyond syllabus. So be forewarned. Students are advised to grasp the basics, then consult a university general chemistry or inorganic chemistry textbook.

** The toughest questions can be found from this chapter, which many teachers rush through due to insufficient time. Much reading is required.


Please note that the color spectrum and its related frequencies, wavelength, crystal field theory, Kstab are not discussed in these notes. You may want to study these concepts as this topic are highly important.

My notes are incomplete; I hope to improve on this post as this has turned out to be a popular post.
