Tetrahedral Complexes When there are?four coordinate bonds?the complexes often have a?tetrahedral?shape Complexes with four?chloride?ions?most commonly adopt this geometry Chloride ligands a...
Octahedral Complexes Octahedral?complexes are formed when a central metal atom or ion forms?six coordinate bonds This could be six coordinate bonds with?six?small,?monodentate?ligands Exampl...
Monodentate ligands Monodentate?ligands can form only?one?dative bond to the central metal ion This is because they have a single lone pair of electrons to form a dative bond with the metal ...
Coloured Ions Perception of colour Most transition metal compounds appear coloured. This is because they absorb energy corresponding to certain parts of the visible?electromagnetic spectrum ...
已經下定決心做一個EPQ項目，卻呆坐在一個空白的電腦屏幕前，不知從何入手... ...這是不是你？EPQ的全稱是Extended Project Qualification，是A-Level課程以外的獨立研究項目，涉及到大量寫作、計劃和自我激勵。e...
Transition Metal Complexes Transition element ions can form complexes which consist of a?central metal ion?and?ligands A ligand is a molecule or ion that forms a co-ordinate bond with a tran...
General Properties of Transition Metals Transition metals are elements with an incomplete d-subshell that can form at least one stable ion with an incomplete d-subshell This definition disti...
Redox Titration Calculations Redox Titrations In a?titration, the concentration of a solution is determined by titrating with a solution of known concentration. In redox titrations, an?oxidi...
Fuel Cells A fuel cell is an electrochemical cell in which a fuel?donates?electrons at one electrode and oxygen?gains?electrons at the other electrode These cells are becoming more common in...
