Define d-block element?
Electronic configuration differs from previous elements by electrons filling the d-shell
5 of 8
Define a Ligand, and what they do.
Ligand: A ligand is a species that can donate a lone pair of electrons to form a covalent bond. What they do: They from a complex ion by having a metal ion in the centre with a number of LIGANDS surrounding it.
6 of 8
Define Coordination Number.
Coordination number is the number of ligands that bond to the metal.
7 of 8
What is the Coordination number of H20, NH3 and Cl-? and what shape do they make?
Coordination number: 6 for each (because they are simple ligands). and they form an octahedral shape.
