The ideal gas laws are based on a model in which the ideal gas is composed of molecules which neither attract nor repel each other. The pressure that the ideal gas exerts on its container is simply the result of the random thermal motion of the molecules and the continual collisions which result from that random thermal motion. If the molecules also repelled each other, then they would produce a gas with even higher pressure, and the pressure would also increase more rapidly, if the gas was compressed, than it does in the absence of such repulsion. The observed behavior of real gases is much closer to that of an ideal gas that does not include repulsion between molecules. No such repulsion has been observed.

What is the definition of VESPR Theory?
VSEPR theory stands for Valence Shell Electron Pair Repulsion theory. It is a model used to predict the geometry of molecules based on minimizing the repulsion between electron pairs in the valence shell of an atom. By considering the repulsions between electron pairs, VSEPR theory helps determine the shape of molecules.
What is a VSEPR model of molecular bonding?
The VSEPR (Valence Shell Electron Pair Repulsion) model is a theory used to predict the shape of molecules based on the repulsion between electron pairs around a central atom. It states that electron pairs will arrange themselves in a way that minimizes repulsion, leading to specific molecular geometries. By considering the number of bonding and lone pairs around the central atom, the VSEPR model helps determine the shape and bond angles of molecules.
What does the dotted line between the water molecules represent?
The circles are actually the letter "O". O is the symbol for Oxygen.
What decides how molecules behave?
The behavior of molecules is primarily determined by their chemical structure, which includes the types of atoms they contain and how they are arranged. Interactions such as bonding and forces between molecules also play a crucial role in their behavior. Factors like temperature, pressure, and the surrounding environment can also influence how molecules behave.
Why are a molecule's atmos as far away from each other as they can get?
Molecules naturally arrange themselves in a way that minimizes potential energy. By being as far apart as possible, the molecules can reduce the electrostatic forces of repulsion between them, which helps stabilize the overall structure of the molecule. This maximizes the stability and energy efficiency of the system.
What is the charge on an electron and how does it affect the behavior of atoms and molecules?
The charge on an electron is negative. This charge affects the behavior of atoms and molecules by influencing how they interact with each other through attraction and repulsion. Electrons play a key role in forming chemical bonds between atoms, which determine the structure and properties of molecules.
What is the attractive forces between like molecules?
Cohesive force is the attractive force between like molecules. Cohesive forces are also known as intermolecular forces and can also be repulsion forces.
What is the definition of VESPR Theory?
VSEPR theory stands for Valence Shell Electron Pair Repulsion theory. It is a model used to predict the geometry of molecules based on minimizing the repulsion between electron pairs in the valence shell of an atom. By considering the repulsions between electron pairs, VSEPR theory helps determine the shape of molecules.
Do molecules touch each other in a solid state?
In a solid state, molecules are packed closely together but they do not touch each other in the traditional sense. There is a small distance between molecules due to the forces of attraction and repulsion between them.
How does a lone pair distort the molecualr shape?
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
What role does repulsion play in the field of biology?
In biology, repulsion plays a key role in various processes such as cell division, immune response, and interactions between molecules. Repulsion helps to maintain the structure and function of biological systems by preventing certain molecules or cells from coming into close contact or interacting with each other. This allows for proper organization and functioning within living organisms.
What general shape do water molecules have?
Water molecules have a bent or V-shape due to the repulsion between the lone pairs of electrons on the oxygen atom.
What does electrostatic force do?
It makes electrical charges attract one another, or repel one another.
What is ion-ion and ion -solvent interaction?
Ion-ion interactions involve the attraction or repulsion between charged ions, which are influenced by the charges and sizes of the ions involved. Ion-solvent interactions pertain to the interactions between ions and solvent molecules, where the solvent molecules surround and solvate the ions due to their charges. These interactions play a crucial role in determining the properties and behavior of ions in solution.
What is between like charges?
"repulsion"
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.
What does repulsion mean in science terms?
In science, repulsion refers to the force between two like-charged particles or objects that causes them to push away from each other. It is a fundamental principle of electromagnetism and is crucial in understanding the behavior of charged particles in various physical systems.
