Which of these forces is an attractive force between two atoms?

What is an attractive force between two atoms?

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds and may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds. The strength of chemical bonds varies considerably.

What causes the attractive force between two atoms?

London dispersion forces are intermolecular forces that occur between all atoms and molecules due to the random motion of electrons. For example, the electron cloud of a helium atom contains two electrons, and, when averaged over time, these electrons will distribute themselves evenly around the nucleus.

What attractive and repulsive forces are involved when two atoms are brought close together?

When two atoms come closer together, the positively-charged nucleus of one atom exerts an attractive force on the negatively-charged electrons of another atoms. Meanwhile, repulsive forces occur between the nuclei of the two atoms involved as well as the electrons of each atom (similar charge repels).

What are the forces that hold an atom together?

Chemical bonds are forces that hold atoms together to make compounds or molecules. Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.

What are attractive forces?

1. attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.

How do you find attractive forces?

Ions exhibit attractive forces for ions of opposite charge — hence the adage that “opposites attract.” The force of attraction between oppositely charged ions follows Coulomb’s law: F = k * q1 * q2 / d2, where F represents the force of attraction in Newtons, q1 and q2 represents the charges of the two ions in coulombs …

What is the force of attraction called as?

The force of attraction between the same kind of molecules is called the force of cohesion. The force of attraction between different kinds of molecules is called the force of adhesion.

What is the attraction between two like molecules?

An attraction between molecules of the same substance is called cohesion. One of the most common examples of cohesion exists between water molecules,…

What causes molecule attraction?

Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule. Unlike covalent bonds between atoms within a molecule ( intramolecular bonding), dipole-dipole interactions create attractions between molecules of a substance ( intermolecular attractions).

What is the relationship between attractive force and repulsive force in case of two atoms approaching each other?

(13/14) “A chemical bond is a stable state between two atoms or two molecules that attract each other with a force that equals the force that they repel each other.”
