What happens to atoms when they touch?

When two atoms touch i.e, their outer orbits come near each other then generally they share their electrons to form bonding and acquire a more stable state. In case of physical touching which is generally not possible as the outer shell electrons repel each other.

Is touch a repulsive force?

We learnt that touching is the repulsive force between atoms and that two things are never really in contact. Are there things with a repulsive force strong enough for us to see that we can’t touch it?

Why is there a repulsion between the atoms?

Repulsive forces Repulsive forces exist only when atoms are very close to each other. One atom’s energy level cannot invade the energy level of another atom.” There is a distance between atoms; they cannot be attached to each other.

Why do atoms attract and repel?

Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Do things ever really touch?

Well, technically speaking​, you can’t actually touch anything. This is because the electrons in the atoms that make up your finger and that of the object you’re trying to touch repel each other (according to the basic law of electrostatics).

Can we actually touch things?

What happens when two atoms get closer to each other?

From that point on, if the two atoms get even closer, their PE will increase (and what about their KE?) because the repulsions between the two nuclei will become more and more intense (what about electronic repulsions?

How do protons and Electrons attract and repel each other?

That is, a proton and an electron will attract each other. The closer they are together, the stronger this attraction will be. Two protons (or two electrons) will repel each other. And again, the closer together they are, the stronger the repulsion. Now the nucleus of an atom is positively charged,…

Why do particles move apart when they are close together?

If they can’t get that close, the strong force is too weak to make them stick together, and other competing forces (usually the electromagnetic force) can influence the particles to move apart. This is represented in the following graphic.

What happens to potential energy when force is attractive?

The forces are attractive, so if you consider the force of atom A pulling on atom B, the force exerted by atom A on atom B is toward atom A. If atom B moves in that direction (toward atom A), the potential energy will decrease.
