WebThe main postulates of Bohr’s Atomic Model are as follows: The electrons move around the nucleus in certain permitted circular paths known as orbits. Each orbit is associated with a definite amount of energy and therefore, these are known as energy levels or energy states. WebWerner produced a theory to explain the structures, formation and nature of bonding in the coordination compounds. He postulated that metals exhibit two types of valencies (i) …
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.
WebPostulates of Werner’s theory: a. Two types of valencies are shown by most metallic elements: Primary valence or principal valence. Secondary valence. b. The tendency of every metal is to satisfy both primary and secondary valences. c. The number of secondary valence shown by each metal is fixed. gifts to take to japanWeb1925 (Heisenberg): Werner Heisenberg formulated a version of quantum mechanics that made use of matrix mechanics.
