This theory is given by alfred werner in 1892. The main postulates of this theory are as follows.
1) in the coordination compound the metal show two types of valancies
or linkage these are called primary and secondary valancies .
2)the primary valancies are normally ionisable and are represented
by the oxidation number and are satisfied by negative ions.
3) the secondary valancies are non - ionisable and are satisfied by neutral moleclues and negative ions. They are represented by coordination number and fixed for an atom.
4) the secondary valancies are directed towards the fixed positions in space . It leads to definite geometrry of the complex compound . On the other hand primary valancies are non-directional.....

Name of the scientist that came up with the continental drift hypothesis?
Did you mean Plate Tectonics Theory? - Plate Tectonics Theory is the combination of Continental Drift and Ocean/Sea Floor Spreading. BTW. The scientist who started it is Howard Baker continued by Alfred Wegener.
Explain who proposed the continental drift theory?
Alfred Wegener proposed the theory of continental drift at the beginning of the 20th century. His idea was that the Earth's continents were once joined together, but gradually moved apart over millions of years. The idea was rejected at first as he was a Meteorologist and not regarded as a proper scientist.
What did Alfred Russell Wallace do as a scientist?
He proposed the theory of evolution by natural selection, independently of Darwin.
Who is the father of coordination chemistry?
Alfred Werner is considered the father of coordination chemistry for his work on the theory of the structure of coordination compounds, specifically his coordination theory.
What is werner's theory?
Werner's theory, proposed by Alfred Werner in 1893, was the first attempt to explain the bonding in coordination compounds. It suggested that metal ions can form coordination complexes by donating electron pairs to coordinate covalent bonds with surrounding ligands. This theory laid the foundation for modern coordination chemistry.
What is Alfred Werner's theory?
Alfred Werner suggested in 1893 that metal ions exhibit what he called primary and secondary valences. - Primary valences were the oxidation number for the metal (+3 on the cobalt at the right). - Secondary valences were the coordination number, the number of atoms directly bonded to the metal (6 in the complex at the right).

How has Alfred werner's research has changed our lifestyle today?
Alfred Werner has played a major role in the advancement of atomic physics. He worked to derive compounds by focusing on a theory of coordination, in which addition and insertion compounds and auxiliary and principal valencies have been used.
Why did other scientists not accept Alfred Wegeners theory?

Who proposed the continental drift theory in the 1900?
Alfred Wegener
What has the author Alfred O'Rahilly written?
Alfred O'Rahilly has written: 'Electromagnetic theory' 'Electromagnetics' -- subject(s): Electromagnetic theory
Who had the theory of pangea?

Was Alfred wegner theory?
Nope
What is Alfred Wallace's theory and what evidence did he use to develop it?
Charles Darwin and Alfred Russel Wallace proposed the theory called Natural Selection. This theory explained evolution.
What is the compound XeCl8?
XeCl8 does not exist as a stable compound. Xenon typically forms compounds with a maximum coordination number of 6 due to its electron configuration, and the reported compound XeCl8 is likely a theoretical or unstable concept.
What theory did Alfred wegner introduce?
Alfred Wegener introduced the theory of continental drift, which proposed that Earth's continents were once joined together as a single supercontinent called Pangea and have since moved to their current positions. This theory laid the foundation for the development of the modern theory of plate tectonics.
