The weak and strong nuclear forces are the main reasons
Strong nuclear forces act through gluons in the nucleus
The nucleus consists of protons and neutrons. Inside the nucleus, there is an electrostatic force of repulsion between the protons. Those protons have positive charges, and like charges repel. Also acting in the nucleus is a force of attraction called the nuclear force. It provides the nuclear binding energy to keep the nucleus together. This nuclear force is a short range force, and is so strong that it will overcome the effect of the force of repulsion between the protons.
Such an element is radioactive and to stabilised itself its nucleus emits the alpha and beta particles along with gamma rays till it is converted into a stable nucleus.
A nucleus is stable if the electrostatic and strong nuclear forces balance out.
Strong nuclear forces hold the nucleus together: the nucleus is actually enveloped in what can be described as a nuclear envelope.
The inter nuclear forces bind the atoms and nucleus together . This force is the cause for the nucleus binded towards the atoms.
intermolecular forces
2 of them : the strong and weak nuclear forces.
the strong force
There are 4 types of forces: gravity, electromagnetic, strong, and weak. Atoms are held together by electromagnetic forces, the nucleus is held together by the strong force. The nucleus contains neutrons and protons which are made up of quarks, which are held together by a type of strong force called a gluon.
The nucleus is held together by a combination of both the strong and weak forces.The electrons are held in their orbitals about the nucleus by the electromagnetic force.That leaves only gravity, which does not participate in holding atoms together.
Strong nuclear forces hold the nucleus of an atom together. Weak nuclear forces are involved when certain types of atoms break down.
The weak and strong nuclear forces are the main reasons
The repelling forces you are referring to are from electrical charges and are much weaker than the nuclear forces that hold the particles (protons and neutrons) together in the nucleus.
strong nuclear force. The nucleus is held together by both the strong nuclear force and the weak nuclear force. The electron is bond to the nucleus by electro-static forces.
