What are the atomic similarities and differences between solids liquids and gases?

Solid, Liquids, and Gases. Sold, liquid, and gas all have volume and shape. They are all made up of atoms, molecules, or ions. Liquids and solids can be referred to as condensed phased because their particles are close together. Liquids and gases flow easily because their particles can move or slide past one another.

What are the major differences between solids liquids and gases in terms of intermolecular forces?

The molecules of a gas move apart when they collide. The average kinetic energy of the particles in a liquid (or solid) is small enough that the forces of attraction between them is sufficient to hold the particles close together. The molecules in a liquid (or solid) do not move apart.

What is London dispersion forces example?

London Dispersion Forces Example For example, consider London dispersion forces between two chlorine molecules. Here both chlorine atoms are bonded through a covalent bond which forms by equal sharing of valence electrons between two chlorine atoms.

Is nitrogen gas a London dispersion?

Nitrogen gas (N2) is diatomic and non-polar because both nitrogen atoms have the same degree of electronegativity. London dispersion forces allow otherwise non-polar molecules to have attractive forces. However, they are by far the weakest forces that hold molecules together.

Which gas has the weakest London dispersion forces?

The dispersion forces are progressively weaker for bromine, chloride, and fluorine; this is illustrated in their steadily lower melting and boiling points. Bromine is a liquid at room temperature, while chlorine and fluorine are gases whose molecules are much further apart from one another.

Is hydrogen bonding stronger than London dispersion?

In hydrogen bond – hydrogen atom of one molecule binds to the nitrogen, oxygen or fluorine atom with a lone pair of electrons of another molecule. It is easy to remember with the abbreviation. H-bonds are stronger than London dispersion forces, but not as strong as covalent or ionic bonds.

Which is stronger dipole or hydrogen?

Although a hydrogen bond is much stronger than an ordinary dipole-dipole force, it is roughly one-tenth as strong as a covalent bond between atoms of the same two elements.

What is the relationship between polarizability and dispersion forces?

Polarizability affects dispersion forces in the following ways: As polarizability increases, the dispersion forces also become stronger. Thus, molecules attract one another more strongly and melting and boiling points of covalent substances increase with larger molecular mass.
