The observed geometry reflects the attempt to minimize electron–electron repulsion by maximizing the distance between electrons. Bond angles are determined solely by the number of valence electrons around a central atom. It is instructive to use examples…...
The meaning of VALENCE SHELL is the outermost shell of an atom containing the valence electrons.
To explain the title "Valence Shell Electron Pair Repulsion," let's do a some review. The valence shell is the outer shell of electrons that are involved in bonding. Valence comes from the same word as "Valiant" meaning courageous and strong. In chemistry, it is these outer electrons that...

First,determine the number of electrons in the outer (valence) shell about the central atom (C, N, Xe, I, etc.): Carbon, for example has four valence electrons, nitrogen 5, etc. Second,find valency and number of electrons associated with the ligandX: ...
Molecular geometry is determined by possible locations of an electron in a valence shell, not by how many how many pairs of valence electrons are present. To see how the model works for a molecule with double bonds, consider carbon dioxide, CO2. While carbon has four pairs of bonding electro...
Answer and Explanation:1 The electrons of an atom are arranged in energy levels. These levels are called shells. The outermost shell is the valence shell, and valence... Learn more about this topic: Valence Electrons | Definition, Role & Examples ...
Energy loss spectra of 2.5 keV electrons, scattered through small angles by CF4, have been obtained in the region of valence, carbon K- and fluorine K-shell excitations. The carbon K-shell spectrum has features which may be associated with the existence of an effective potential barrier in ...
