Mar 22, 2011 · The nucleus of the atom contains protons charged with positive electricity. These positive charges repel each other. The miracle of creation occurs when protons adhere to each other forming a single point. The power that confines the protons repelling each other and the neutrons within a single point is immense; it is called strong nuclear force.
Key idea: Nuclei are held together, against the electrostatic repulsion trying to tear them apart, by the nuclear force, a (generally) attractive, but short-range, force between nucleons (neutrons and protons). Related End-of-Chapter Exercise: 16. The force that holds a nucleus together is the nuclear force, a short-range force between nucleons.
The protons of an atom are all crammed together inside the nucleus. Each proton carries a positive charge, and like charges repel each other. However, forces in the nucleus counteract this repulsion and hold the nucleus together. (Physicists call these forces nuclear glue.
The force between quarks is carried by gluons through a special charge called color (red, blue or green). Protons and neutrons are comprised of three valence quarks held together by the exchange of gluons, along with a quark-gluon "sea" of particles that constantly pop into and out of existence.
It is also the strongest force of the four. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Its main purpose is to hold together the subatomic particles of the nucleus (protons, which carry a positive charge, and neutrons, which carry no charge).
What kind of forces hold the protons and neutrons together in the nucleus? Asked by: Madhur Answer It seems that since all protons are positive, they would repel each other, and the nucleus would fly apart. Fortunately, there is a force that holds it together. Any force that you can think of goes into four different categories.
Protons and neutrons in the nucleus are held together by a strong nuclear force. This strong nuclear forceis a short-range force that acts as an attractive force for protons and neutrons. When the nucleus is small (contains smaller number of protons and neutrons), the nuclear force is stronger, and the atom is more stable.
