Positive ions in a crystal repel each other
the VSEPR theory
Electron pairs
Tertahedral
Linear
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
The correct answer is: Why molecules have different shapes.
The correct answer is: Why molecules have different shapes.
According to VSEPR theory, molecules adjust their geometry to keep the electrons in valence shells as far apart from each other as possible.
VSEPR theory
VSEPR is valence spin electron pair repulsion, and helps in describing the electron domain geometry and the molecular geometry of a substance.
How atoms are arranged in a molecule.
IF7 is pentagonal bipyramidal
VSEPR-Valence Shell Electron Pair Repulsion
The geometry of molecules. In this theory the valence electron pairs around an atom repel one another.
In this theory, electron pairs in the central atom repell one another and tend to space themselves as far apart as they can. This spacing on a 3 dimensional model gives rise to the various shapes of molecules.
