Electron pool theory was proposed by Gilbert Lewis. He suggested that in certain chemical reactions, electrons are shared and not tied to specific atoms, forming a "pool" of electrons that can be used by multiple atoms. This theory played a significant role in the development of our understanding of chemical bonding.

What is the difference between free electron theory and nearly free electron theory?
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
In which year was transmission electron microscope was invented?
The transmission electron microscope was invented in 1931 by German engineers Ernst Ruska and Max Knoll.
Was the electron microscope invented by a Canadian?
No, the electron microscope was not invented by a Canadian. The electron microscope was invented by German physicist Ernst Ruska in 1931, along with Max Knoll. The invention revolutionized microscopy by using a beam of electrons to illuminate specimens, allowing for much higher magnification and resolution compared to traditional light microscopes.
What is repelled in the VSEPR theory?
In the VSEPR (Valence Shell Electron Pair Repulsion) theory, electron pairs around the central atom repel each other in space, leading to a molecular geometry that minimizes repulsion and maximizes stability. This repulsion between electron pairs helps determine the shape and bond angles of molecules.
When was the electron microscope invented?
1928 i believe by the Germans... someone check me on that... it wasnt the electron microscope we know today but it was the same concept only it magnified by a small 17 times... it has be improved since then
Who invented the electron cloud theory?
Rutherford.
Free-electron theory of metals is used for?
write note on free electron theory
What is meant by electronic theory?
Electronic theory is the theory of the behavior of the electron under various conditions including a free electron, a bound electron in either an outer or inner orbit of the atom.
Who the pool ball theory was invented by?
The pool ball theory, often associated with discussions of chaos theory and complex systems, was popularized by physicist Edward Lorenz in the 1960s. While it may not have been "invented" in a formal sense, Lorenz used the metaphor of pool balls colliding to illustrate how small changes in initial conditions can lead to vastly different outcomes, highlighting the sensitivity of dynamic systems. This concept is fundamental to understanding chaotic behavior in various fields, including meteorology and economics.
When was the electron tube invented?
Lee De Forest invented the electron tube in 1906.
Who invented the electron?
Nobody "invented" the electron cloud. The concept was discovered by Werner Heisenberg in 1926.
Use the electron theory to explain how insulators and conductors work?
the same way an insulator and a conductor will work with out the electron theory!
When was the electron micoscope invented?
1608 was when the Microscope was invented.
Is there a unified theory explaining all correlated electron systems?
There is no single unified theory that explains all correlated electron systems.
What is quantum free electron theory of metal?
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
When was the scanning electron microscope invented?
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
What does the electron cloud theory state?
an atom
