State the rules to name mononuclear coordination entities.

(N/A) . Rules to name ions: If the coordination entity is anionic,the name of the cation is written first,followed by the name of the anionic complex.
For example: In $K_{2}[HgI_{4}]$,the name of $K^{+}$ is written first,followed by the name of $[HgI_{4}]^{2-}$. If the coordination entity is cationic,the name of the positive part is written first,followed by the name of the anion.
For example: In $[Ag(NH_{3})_{2}]OH$,the name of the positive ion $[Ag(NH_{3})_{2}]^{+}$ is written first,followed by the name of the anion,i.e.,$OH^{-}$ ion.
$B$. Rule to name ligands: If the ligands are anionic,the name must end with the suffix $-o$. If the ligands are neutral,they are given the same name as the uncoordinated molecule.

$Cl^{-}$ : Chlorido	${}^{-}NH_{2}$ : Amido
$Br^{-}$ : Bromido	$-NC$ : Isocyano
$I^{-}$ : Iodido	$-SCN$ : Thiocyanato
$-CN$ : Cyanido	$-NCS$ : Isothiocyanato
$-OH$ : Hydroxo	$ONO^{-}$ : Nitrito
$H^{-}$ : Hydrido	$SO_{4}^{2-}$ : Sulphato
$O^{2-}$ : Oxo	$SO_{3}^{2-}$ : Sulphito
$O_{2}^{-}$ : Superoxo	$PO_{4}^{3-}$ : Phosphato
$O_{2}^{2-}$ : Peroxo	$CO_{3}^{2-}$ : Carbonato
$S^{2-}$ : Sulphido	$CH_{3}COO^{-}$ : Acetato
$N_{3}^{-}$ : Azido	$C_{2}O_{4}^{2-}$ : Oxalato
