VSEPR theory predicts the molecular geometry of a molecule by considering the repulsion between electron pairs around the central atom. In the case of SF4, there are five regions of electron density around the sulfur atom, leading to a trigonal bipyramidal geometry. However, one of the regions is a lone pair, causing greater repulsion and pushing the fluorine atoms closer together, resulting in a see-saw shape for SF4.

What in VSEPR theory?
VSEPR stands for Valence Shell Electron Pair Repulsion, and it describes how valence (bonding) electrons are arranged around an atom, and how they are used in creating a bond. This then can be used to help predict the GEOMETRIC SHAPE of the molecule being formed.
Would the big bang theory help explain the shift?
I presume the question refers to the "redshift" of distant galaxies. Actually it is the other way around - i.e. the Doppler redshift helps to support and explain the Big Bang Theory. This "redshift" is called the "cosmological redshift". Strictly speaking, it's not the Doppler effect.
What is the kinetic theory of matter for radiation?
The kinetic theory of matter for radiation states that radiation consists of particles (photons) that move at the speed of light and transfer energy when they interact with matter. This theory helps explain how radiation behaves in terms of absorption, emission, and scattering processes.
How did quantum mechanics change our understanding of atoms?
Quantum mechanics explained principles like superposition of wave-particle duality of mater. It shaped a world where the classical laws of physics were merely a waste. It exposed to us a world of particles, that matter was made of many groups of particles each accomplishing a particular task just like our organs. With the help of quantum mechanics we were able to get a 3 dimensional idea of the atom. It was able to explain the screening effect and the stark effect. It was also able to construct exact shape of orbitals and explain the formation of various types of compounds( A theory called hybridization and VSEPR and MOT came in handy thanks to quantum mechanics). It also explained the idea that atoms were composed of a lot more particles and helped predict their states nature and characteristics.
What are the three of the many possible shapes of molecules?
Without given a specific molecule there is not any way to determine the shape. Beryllium chloride consists of beryllium in the middle and a chlorine on each side, and is in the shape of a straight line.
How does the VSEPR theory explain molecular shape?
Electron pairs repelling each other push atoms apart.
What in VSEPR theory?
VSEPR stands for Valence Shell Electron Pair Repulsion, and it describes how valence (bonding) electrons are arranged around an atom, and how they are used in creating a bond. This then can be used to help predict the GEOMETRIC SHAPE of the molecule being formed.
What does the VESPR theory help predict?
The VSEPR theory helps predict the shapes of molecules based on the arrangement of electron pairs around the central atom. It allows us to determine the bond angles and overall geometry of a molecule, which in turn influences its physical and chemical properties.
The theory of tectonic plates help to explain?
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
What theory would help a microbiologist explain the basic structure of a microscopic organism?
the theory of evolution
What did bohr's theory help explain?
atoms combine to form molecules
How do Lewis structures help predict the shape of a melocule?
Look at double bonds and dotted valence. Double or more bonds equals a linear shape. Also... 2 bonds = linear 3 bonds = linear if dbl or trpl bonded, otherwise bent 4 bonds = triginal poly Etc.
How does the movement of particles in a liquid help explain the shape and volume of liquids?
They dont
How does VSEPR determine molecular geometry?
The VSEPR model has enabled chemists and students to describe, explain, and predict more easily the stereochemistry of chemical elements and compounds. The Lewis structure, which was primarily used to convey the appearance of molecules in the past, proved to be inadequate because there existed many exceptions to this type of diagram. The Lewis structure displayed no information about the geometry of a molecule as it did not indicate how atoms were arranged in space. The VSEPR theory has relieved chemists and students of such limitations by describing the orientation of a molecule in relation to the Pauli principle. By determining this principle affected molecular geometry, Gillespie illustrated that the repulsion interactions of all electron pairs, both shared and unshared ones, in the valence of a molecule determine its shape. This is due to the fact that electron pairs adapt an arrangement that keeps them as far apart as possible; they repel one another. glad to help grade 12 chem student
How do the positions and movements of particles in a liquide help to explain the shape and volume of the liquid?
because it nothing
What are the four theories of prejudice?
The four theories of prejudice are realistic conflict theory, social identity theory, authoritarian personality theory, and intergroup contact theory. These theories help to explain the origins and perpetuation of prejudice within society.
How does the movement of particles in a liquid help to explain the shape and volume in a liquid?
Because its particles are free to move, a liquid has no definite shape. However, it does have a definite volume.
