Why do the atoms repel each other after a certain point of closeness?

If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii. If the atoms get two close then the nuclii will repell each other. Because the electrons are attracted to both nuclii pulling the two atoms apart would require energy.

Why do atoms attract each other when they are little away from each other?

The valence electrons are involved in bonding one atom to another. The attraction of each atom’s nucleus for the valence electrons of the other atom pulls the atoms together. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which “share” the electrons.

What causes atoms to be attracted to each other?

The atoms attract each other due to the force exerted by the nucleus of the atoms. In the beginning, the nuclear force (i.e. the force exerted by the protons present in the nucleus of one atom on the electrons of the other atom) dominate th repulsive forces between the electrons of the two atoms.

Why are two atoms attracted to each other when they start to move closer?

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. As the atom gets closer, the net force of attraction increases. At a certain optimal distance, the net attractive force is maximized.

Why do molecules attract?

The difference between the number of electrons and protons in an atom determines how strong the charge is, and what that atom can bond with. Atoms with a positive charge will be attracted to negatively charged atoms to form a molecule. This bonding between atoms is the key to how molecules interact with each other.

Why do atoms attract electrons?

An atom’s electronegativity is affected by both its atomic number and the size of the atom. The higher its electronegativity, the more an element attracts electrons. The nuclear charge is important because the more protons an atom has, the more “pull” it will have on negative electrons.

How molecules are attracted to each other?

Atoms are the building blocks of chemistry. Each atom contains negatively and positively charged particles (electrons and protons). Atoms with a positive charge will be attracted to negatively charged atoms to form a molecule. This bonding between atoms is the key to how molecules interact with each other.

How do molecules bond to each other?

When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. In a covalent bond, electrons are shared between atoms. The bonds between the two hydrogen atoms and the oxygen atom in a molecule of water are covalent bonds.

Which molecules are attracted to each other?

When two particles experience an intermolecular force, a positive (+) charge on one particle is attracted to the negative (-) on the other particles. When intermolecular forces are strong the atoms, molecules or ions are strongly attracted to each other, and draw closer together.

Do molecules repel each other?

Attractive forces: At very close distances, all molecules repel each other as their electron clouds come into contact. The more electrons in the molecule (and thus the greater the molecular weight), the greater is this attractive force.

Why do electrons repel each other?

When you have two electrons, the combined electric fields result in a higher and higher potential energy as they get closer. In order to minimize the potential energy, they repel each other (in the case of a positive and negative charge, potential energy is minimized by bringing them together, so they attract).
