In a covalent bond, atoms share one or more pairs of electrons, forming a strong bond between them.

Hydrogen bonding is a strong intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative atom, such as oxygen or nitrogen.

Solids have a definite shape and volume, and their particles are closely packed together, resulting in a high density.

Evaporation is the process by which a liquid changes into a gas, typically occurring at the surface of the liquid.

Gases have a low density, are highly compressible, and do not have a definite shape, taking the shape of their container.

Metallic bonding is the force that holds the atoms of a metal together, resulting in a strong, rigid structure.

In an ionic bond, one atom transfers electrons to another atom, creating positively and negatively charged ions that attract each other.

Dipole-dipole interactions are intermolecular forces that occur between polar molecules, where the positive end of one molecule attracts the negative end of another molecule.

Liquids have a definite volume but take the shape of their container, indicating that they have an indefinite shape.

Condensation is the process by which a gas changes into a liquid, typically occurring when the gas is cooled.

Solids have a high density, are not easily compressed, and have a definite shape, maintaining their own structure.

London dispersion forces are intermolecular forces that occur between all molecules, regardless of their polarity, due to the temporary fluctuations in electron distribution.

Gases have an indefinite shape, taking the shape of their container, and are highly compressible.

Melting is the process by which a solid changes into a liquid, typically occurring when the solid is heated.

Liquids have a high density, are not easily compressed, and take the shape of their container.
