1. ligand - e) electron pair donor.

2. coordination compound - f) a charged species consisting of a metal ion surrounded by ligands.
3. Lewis base - c) a neutral molecule or charged ion that acts like a Lewis base by donating a lone pair of electrons that can be used to form a bond to a metal ion.
4. complex ion - a) a ligand that can form two bonds (donate two electron pairs) to a metal ion.
5. bidentate ligand - a) a ligand that can form two bonds (donate two electron pairs) to a metal ion.
6. octahedral complex - d) a metal ion surrounded by six ligands in an octahedral geometry.

To match the terms with the correct definitions, it would be helpful to understand the meanings of each term. Let's break down each term individually:

1. Ligand: A ligand is a molecule or ion that can donate a pair of electrons to a central metal ion to form a coordinate bond. Ligands typically have one or more lone pairs of electrons to donate.

2. Coordination Compound: A coordination compound is a compound composed of a central metal ion surrounded by ligands. It can be neutral or charged, and the ligands are attached to the central metal ion through coordinate bonds. Counter ions may be present to balance the charge.

3. Lewis Base: A Lewis base is a molecule or ion that donates a lone pair of electrons to form a coordinate bond with a Lewis acid. In the context of coordination compounds, ligands act as Lewis bases by donating electron pairs to the central metal ion.

4. Complex Ion: A complex ion is a charged species formed by a central metal ion surrounded by ligands. Complex ions can be either positively or negatively charged, depending on the overall charge of the ligands and the central metal ion.

5. Bidentate Ligand: A bidentate ligand is a ligand that can form two bonds or donate two electron pairs to the central metal ion. Typically, bidentate ligands have two donor atoms that can simultaneously coordinate with the metal center.

6. Octahedral Complex: An octahedral complex is a coordination compound where the central metal ion is surrounded by six ligands in an octahedral geometry. This means that the ligands are arranged around the metal ion in a symmetric manner, forming a regular octahedron.

Now, let's match the terms with the correct definitions:

1. Bidentate Ligand - a) a ligand that can form two bonds (donate two electron pairs) to a metal ion.
2. Coordination Compound - b) a neutral compound (often containing a transition metal) consisting of a complex ion and counter ions.
3. Lewis Base - c) a neutral molecule or charged ion that acts like a Lewis base by donating a lone pair of electrons that can be used to form a bond to a metal ion.
4. Octahedral Complex - d) a metal ion surrounded by six ligands in an octahedral geometry.
5. Ligand - e) electron pair donor.
6. Complex Ion - f) a charged species consisting of a metal ion surrounded by ligands.

By matching the definitions to the terms, we have:
1. Bidentate Ligand - a)
2. Coordination Compound - b)
3. Lewis Base - c)
4. Octahedral Complex - d)
5. Ligand - e)
6. Complex Ion - f)
