Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.

∙ 12y ago1) Intermolecular forces are the forces of attraction between molecules.
Intermolecular forces include the London force, induced dipole, dipole-dipole force, and Hydrogen bonding.
London forces exist between all molecules, both polar and nonpolar. Simply put, they are caused by the attraction between the positive nuclei of one molecule for the negative electrons of another another molecule. The larger the molecule, the stronger the London force is.
Dipole-dipole forces occur between polar molecules. The relatively large differences in electronegativity in polar molecules give the molecule partial charges. The less electronegative end is the positive dipole and has partial positive charge, the more electronegative end has a partial negative charge. The negative dipole of one molecule is attracted the the positive dipole of another. Dipole dipole forces are stronger than London dispersion forces.
Hydrogen bonding occurs between a hydrogen atom (bonded to N, O, or F) of one molecule and a highly electronegative atom of another molecule (nitrogen, oxygen, or fluorine). It is the strongest intermolecular force.
2) Even stronger are intramolecular forces-the forces between the atoms within a molecule. Intramolecular forces include ionic bonds, metallic bonds, and covalent bonds. Covalent bonds are generally the most difficult to break.
Ionic bonds usually occur between when the difference in electronegativity between atoms is 1.7 or greater. It involves a transfer of electrons from the less electronegative atom to the more electronegative atom (since more electronegative elements have a greater ability of attracting electron pairs toward itself), so that the less electronegative atom becomes a positive cation and the more electronegative atom becomes a negative anion. The electrostatic attraction between these two oppositely charged ions creates an ionic bond.
Metallic bonds occur between positive metallic cations, which are attracted to their negative delocalized electrons, which move around the positive cations.
Covalent bonds result from the sharing of valence electrons between atoms.

Is a chemical bond a force or a chemical?
Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
Where is the mass found in chemical change?
In the energy because of Einsteins equation: E=mc^2. In a chemical change, mass is converted to energy because of the loss in strong forces and weak forces in molecules.
What is the weakest and most temporary chemical bond?
Van der Waal's forces, or hydrogen bonding.
What are natural forces A Friction B Chemical C Electromagnetic D Gravity?
Friction and gravity
What do the lines in a formula represent?
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.
What are substances that are held together by physical forces not chemical?
Substances held together by physical forces, not chemical
Is chemical an example of natural force?
A chemical compoud or a chemical reaction are not forces.
What is breaking of rock into smaller pieces by gravity or other forces is it chemical weathering or mechanical weathering?
The answer depends on what "other forces" you are talking about. If the other forces are chemical, then weathering can be both chemical or mechanical. Generally, both types occur to various extents.
How are intermolecular forces different from forces that bind atoms together into molecules?
1. Intermolecular forces are the forces between molecules, while chemical bonds are the forces within molecules. 2. Chemical bonds combine atoms into molecules, thus forming chemical substances, while intermolecular forces bind molecules together. 3. Chemical bonding involves the sharing or transferring of electrons, while intermolecular forces do not change the electron stucture of atoms. 4. Intermolecular forces hold objects together, while chemical bonds hold molecules together.
Is magnetic physical or chemical?
Neither properly describes it. All attractions are forces, and there are only four forces in the known universe: gravity, weak nuclear, strong nuclear, and electromagnetic. Magnet attractions are electromagnetic. Both physical forces (that are not gravity) and chemical forces are also classified as electromagnetic forces. So neither physical or chemical properly describes a magnetic force, although classical physics would be more accurate to say than chemical.
What is the weakest type of chemical bonding?
London dispersion forces are the weakest type of chemical bonding.
