transition metals Flashcards
1
Q
complex ion definition
A
-central metal ion, surrounded by ligands to which it is joined by dative covalent / coordinate bonds
2
Q
coordinate/ dative covalent bonding def.
A
the sharing of a pari of electrons with both electrons coming form one/the same atom
3
Q
ligand def.
A
a negative ion/ neutral molecule (like water which has lone pairs) which donates electrons to the central ion
4
Q
monodentate def.
A
a ligand that donates one pair of electrons only
5
Q
coordination number def.
A
number of coordinate bonds
6
Q
octahedral def.
A
the shape of a complex which has a central ion surrounded by six ligands forming an octahedral shape; e.g. [Fe(H2O)6]2+
