What type of attraction occurs between nonpolar covalent molecules?
In non-polar covalent molecules weak forces exists & are known as Van der Waals' forces
What are inter particle forces of attraction?
Inter-particle force, also known intermolecular force, are forces of attraction and repulsion which act between neighboring particles. compared to intramolecular forces, they are a weak force.
The forces between SO2 molecules are known as?
dipole
What is Adhesion and what is Cohesion?
Cohesion ia property of identical molecules to form agglomerates; a common example is the assembly of mercury from small bubbles into a larger one.Adhesion is the attraction between molecules of different chemical nature.
What intermolecular forces are present between to molecules NaCl and water?
There are no molecules of NaCl. NaCl is an "ionic" solid (The bonds have 70% ionic character.) It exists as a network of alternating Na and Cl atoms. When NaCl dissolves in water it ionizes, producing Na+ and Cl- ions, each surrounded by a sphere of water molecules due to the attraction between the charged ion and the polar water molecules.Intermolecular forces, collectively known as van der Waals's forces are attractions between discrete molecules. There are several types of van der Waals forces: London dispersion forces, Debye forces, Keesom forces, and hydrogen bonding. The various kinds of intermolecular forces have a bearing on properties like melting point, boiling point and surface tension to name three.London dispersion forces, which are present between all molecules, are the electrostatic attraction between temporary dipoles. A normally nonpolar molecule can become a temporary dipole due to electron fluctuations withing the molecule.The strength of London dispersion forces are sometimes (erroneously) attributed to variations on molecular weight. The connection between the strength of London dispersion forces and molecular weight is coincidental. The strength of London dispersion forces are a function of the polarizability of the molecule, which in turn, depends on the number of electrons and the surface area of the molecule. The greater the number of electrons, the greater the polarizability and the stronger the London dispersion forces.Dipole-dipole attraction (Keesom forces) exist between molecules which exhibit a permanent dipole moment, that is, molecules which are polar. The positive end of one molecule is electrostatically attracted to the negative end of an adjacent molecule.Debye forces exist between a polar molecule and a nonpolar molecule by inducing a dipole in the normally nonpolar molecule. As a polar molecule approaches a nonpolar molecule, the charged end of polar molecule induces the opposite charge in the nonpolar molecule by either attracting or repelling the electrons in the nonpolar molecule, thus causing electrostatic attractin between the polar and the nonpolar molecule.London dispersion forces and Keesom forces exist between like molecules, as well as unlike molecules. Debye forces only exist between unlike molecules. Of the three, Keesom forces are the strongest, followed by Debye forces and then London dispersion forces. That being said, London dispersion forces can be strong enough to hold large molecular weight alkanes together in the solid state.Hydrogen bonding is unique among molecular interactions due to the formation of a weak covalent bond between adjacent molecules. Hydrogen bonding occurs when hydrogen is internally bonded to N, O or F, and weakly covalently bonded to a N, O or F atom in an adjacent molecule. The hydrogen atom essentially bridges the two molecules. Hydrogen bonding is generally considered the strongest of the intermolecular interactions.

What is the force of attraction between unlike molecules or the attraction between the surfaces of different contacting bodies?
The force of attraction between unlike molecules is known as intermolecular attraction or van der Waals forces. These forces can be categorized as dipole-dipole interactions, hydrogen bonding, or London dispersion forces. The attraction between the surfaces of different contacting bodies is called adhesion and is typically due to intermolecular forces such as van der Waals forces or electrostatic interactions.
What are inter particle forces of attraction?
Inter-particle force, also known intermolecular force, are forces of attraction and repulsion which act between neighboring particles. compared to intramolecular forces, they are a weak force.
What slight attraction that develops between the oppositely charged regions of nearby molecules?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.

Is there force of attraction between molecules of Atoms?
Yes, indeed. These forces are known as intermolecular forces. Molecular solids typically have weak van der Waals forces also known as weak intermolecular forces. Under certain conditions, these bonds can break allowing the element or substance to react.
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 type of attraction exists between the slight positive charge of a hydrogen atom and slight negative charge of a nearby atom?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.

The electrostatic attraction known as hydrogen bonds that form directional intermolecular associations.
The attractive force between masses is known as?
cohesion: the intermolecular attraction between like molecules
