Why there is no repulsion between protons in nucleus?

The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

Why is there a repulsive force 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 does the nucleus not disintegrate in spite of repulsion among the protons?

Explanation: Stability of the nucleus is due to the presence of neutral subatomic particles (neutrons) between the positively charged protons. The neutrons neutralise the repulsion among protons.

Why did the nucleus stay together when we added two neutrons?

The nucleus of an atom is held together by the strong nuclear force that binds together protons and neutrons. It binds together the protons and neutrons in the nucleus. It also holds together the quarks that make up those protons and neutrons and the other hadrons.

Why do atoms approach each other?

The strong attraction of each shared electron to both nuclei stabilizes the system, and the potential energy decreases as the bond distance decreases. If the atoms continue to approach each other, the positive charges in the two nuclei begin to repel each other, and the potential energy increases.

What happens when two atoms molecules collide?

In the first collision, the particles bounce off one another and no rearrangement of atoms has occurred. The second collision occurs with greater kinetic energy, and so the bond between the two red atoms breaks. An effective collision (B) is one in which chemical bonds are broken and a product is formed.

When two atoms approach each other and a bond is formed potential energy?

During the formation of a bond when atoms approach each other the potential energy decreases.

When two atoms are separated and do not attract each other the potential energy is?

Consider two isolated hydrogen atoms that are separated by a distance large enough to prevent any interaction between them. At this distance, the potential energy of the system is said to be equal to zero (see Figure 1).
