Frequent question: Why do particles attract or repel each other?

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

Why do particles attract and repel?

Electromagnetism causes like-charged objects to repel each other and oppositely charged objects to attract each other. The electromagnetic force binds negative electrons to the positive nuclei in atoms and underlies the interactions between atoms. Its force carrier particle is a photon.

Why do particles attract each other?

By an intermolecular force known as the intermolecular force of attraction, particles of matter are attracted to one another. … The force of attraction is not as strong as solids but not as weak as gases in liquids, Liquids are not solid, and they’re not as compressible as gases.

What causes molecules to be attracted or repelled from each other?

More precisely, the positive and negative charges of the hydrogen and oxygen atoms that make up water molecules makes them attracted to each other. … Opposite magnetic poles attract one another much like positively charged atoms attract negatively charged atoms in water molecules.

Do particles both repel and attract each other?

Yes, two charged particles attract each other only if they have opposite charges i.e. One of them is Positive and other is Negative. Opposite charges attract and Like or Similar charges repel each other.

What force attracts particles?


The electromagnetic force can either attract or repel the particles on which it acts. Oppositely charged particles attract each other, while like particles repel one another.

Why do things repel?

Charges that are the same (positive and positive or negative and negative) push each other away, or repel. Charges that are opposite (positive and negative) draw one another together, or attract. An object with an excess of positive charges attracts negative charges until the numbers are equal again.

What two particles attract each other?

The two subatomic particles that are attracted to each other are protons and electrons.

How do particles of matter attract each other?

Take all the above objects and try hammering them, stretching or breaking them. You will observed that you find it easy to break a chalk, little tougher to break rubber band and toughest to break a coin. Conclusion: Particles of matter attract each other.

Do gas particles attract or repel each other?

Gas particles are hard spheres with no internal structure. The volume of the spheres is negligible in comparison to the average distance between particles. The gas particles neither attract or repel one another (they possess no potential energy).

Why do electrons attract each other?

Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. … Since opposite charges attract, protons and electrons attract each other.

Why are atoms attracted to each other in an ionic bond?

Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged. … These oppositely charged ions attract each other to form ionic networks (or lattices).

Why do nonpolar molecules attract each other?

In a nonpolar molecule, the random movement of electrons around the molecule can create temporary, weak dipoles, which induce nearby molecules to also become temporarily polar.

Why do like poles repel?

Like poles of a magnet repel each other. This is because when the two magnets of like poles are kept facing each other the lines of forces are in opposite directions. … When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

Why do like charges repel each other and unlike charges attract each other?

When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced. … Therefore, like charges repel and unlike charges attract.

Why do two objects with the same charge repel?

They repel or attract each other because of their electric field. Positive and Negative charge have electric field in opposite direction. For Ex. Negative charges have electric field towards them.
