transition metals

Goes briefly through most sections of transition metals-hope it helps in your revision!

sorry about the weird notation of substances!- I have used ^ for any charges, some of the incorrect answers are made up words that sound similar :)

HideShow resource information

1. what is the coordinate number

  • the number of different ligan identities within a complex
  • the number of ligands surrounding a transition metal ion
  • the number of dative bonds that form between a transition metal ion and ligands
  • the exact location of teh transition metal ion withint the complex
1 of 20
