This site states that "the current view is that the strong interaction is an interaction between quarks."
It causes the protons in the nucleus repel each other.
The electrical forces inside a nucleus contribute to the nuclear force, also known as the strong nuclear force. This force is responsible for binding protons and neutrons together in the nucleus. It overcomes the electrical repulsion between positively charged protons to hold the nucleus together.
The nuclear force, also known as the strong nuclear force, is caused by the exchange of particles called gluons between quarks inside protons and neutrons. This force is responsible for binding protons and neutrons together in the atomic nucleus.
The two competing fundamental forces inside the nucleus of an atom are the strong nuclear force, which holds protons and neutrons together, and the electromagnetic force, which causes positive charges (protons) to repel each other. The strong nuclear force overcomes the electromagnetic force at close distances, keeping the nucleus stable.
Protons are located inside the nucleus of an atom. The nucleus is composed of protons and neutrons, which are tightly bound together at the center of the atom. Electrons, which have a negative charge, orbit around the nucleus.
The protons are found outside of the neucleus not inside
Protons are found in nucleus inside an atom.
They are found inside the nucleus
The repulsive force inside the nucleus is primarily caused by the electrostatic repulsion between protons, which are positively charged particles. Despite the strong nuclear force that holds protons and neutrons together, the inherent charge of protons leads to a repulsive interaction when they are in close proximity. Additionally, the presence of neutrons helps to mitigate this repulsion by providing an attractive force without adding to the repulsive electrostatic effects, thus stabilizing the nucleus.
Protons are located inside the nucleus.
Inside the nucleus of an atom, tiny particles called protons and neutrons reside. Protons carry a positive charge, while neutrons are neutral, and together they make up the atomic nucleus. These particles are held together by the strong nuclear force, which overcomes the repulsion between the positively charged protons. Additionally, the nucleus is surrounded by electrons, which are much smaller and orbit around the nucleus.
Inside the nucleus of an atom, the primary forces at work are the strong nuclear force and the electromagnetic force. The strong nuclear force, which acts between nucleons (protons and neutrons), is the dominant force that holds the nucleus together, overcoming the repulsive electromagnetic force between positively charged protons. This strong force operates at very short distances, binding nucleons tightly within the nucleus. Additionally, the weak nuclear force plays a role in certain types of nuclear reactions, but it is not responsible for holding the nucleus together.
