WebIn classic philosophy, an axiom is a statement that is so evident or well-established, that it is accepted without controversy or question. [3] In modern logic, an axiom is a premise or starting point for reasoning. [4] In mathematics, an axiom may be a "logical axiom" or a "non-logical axiom". Logical axioms are taken to be true within the ... WebBased on this observation, the following Werner’s theory was postulated: Postulates of Werner’s Theory. The central metal atom in the coordination compound exhibits two types of valency, namely, primary and secondary linkages or valencies.

WebThe postulates of Werner's coordination theory were actually based on experimental evidence rather than theoretical. Although Werner's theory successfully explains the bonding features in coordination compounds, it has drawbacks. Drawbacks: It doesn't explain why only certain elements form coordination compounds.
