Web25 Mar 2024 · The main points of Werner’s co-ordination theory is as follows. ( I ) The central metal or ion in each co-ordination compound has two type valency , namely primary valency or ionisable valency and secondary valency or non-ionisable valency. ( II ) The primary valency of the central metal atom or ion is satisfied by the anions. Web1. Primary valency refers to the oxidation state of metal ion. Secondary valency refers to the coordination number of metal ion. 2. Always satisfied by negative ions. Satisfied by negative ions, neutral molecules or positive ions. 3. These ions are generally written outside the bracket are called counter ions. WebAccording to him-. (a) Each metal in coordination compound possesses two types of valencies : (i) primary valency or principal valencies or ionisable valencies. (ii) Secondary valency or nonionisable valencies. (b) Primary valencies are satisfied by anions only. The number of primary valencies depends upon the. ceiling pot rack with lights
