Give the coordination number and the charge of the central metal ion in each coordination compound: For the charges, enter your answers with the correct sign. e.g. if you think the answer is 1, enter the positive sign followed by the number 1. Na2[Zn(OH)4] coordination number

Answer :

The coordination number shows the number of ligands attached to the central metal.

What is complex in coordination compound?

  • A coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds.
  • Ligands are Lewis bases - they contain at least one pair of electrons to donate to a metal atom/ion.
  • A complex is a coordination compound which contains a central metal atom or ion.
  • The coordination number refers to the number of ligands in the complex.
  • The coordination number usually influences the geometry of the complex compound.

The coordination number and the charge on the central metal in each of the complexes are shown below;

Na2[Zn(OH)4] - The coordination number of the complex is 4 and the charge on the central metal ion is +2.
