Zadanie 7a
Outline what type of bond joins a ligand to the nickel ion and how this bond forms.
Coordination bonds
Identify coordination (dative covalent) bonds in which both shared electrons come from one atom, for example in NH4+, H3O+ and CO, show them with an arrow in Lewis formulas, and at higher level recognise them in transition element complexes.

Zadanie 4d
Glycine, H2NCH2COOH, loses a proton from its carboxyl group in alkaline solution to form the glycinate ion. The glycinate ion can bond to a copper(II) ion through two of its atoms, so it acts as a bidentate ligand. Explain how a glycinate ion bonds to a…
