|
Answer» te!! Here is the answer=================Four postulates on Werners theory------------------------------------------------------♢The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and the SECONDARY valency.♢The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.♢The number of secondary valences is fixed for EVERY metal atom. It MEANS that the coordination number is fixed.♢The metal atom works TOWARDS satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies. |
