Which of the following statements are true concerning stable nuclei?

Check all that apply.

There is no limit to the size of a stable nucleus because of the great strength of the strong nuclear force.

Heavy stable nuclei tend to contain more protons than neutrons.

There is a limit to the size of a stable nucleus because of the short range of the strong nuclear force.

Heavy stable nuclei tend to contain roughly the same number of protons as neutrons.

Heavy stable nuclei tend to contain fewer protons than neutrons.

There is a limit to the size of a stable nucleus because of the short range of the strong nuclear force.

Heavy stable nuclei tend to contain roughly the same number of protons as neutrons.

Explanation:

An atomic nuclei consist of nucleons which are protons and neutrons that occupies the central part of atoms.

A stable nuclei is one in which the number protons and neutron have roughly the same number. In an unstable nuclei, the proton or the neutron number balance is tipped. This imbalance is what results in radioactively and causes some of these nuclear particles to be radiated. The decay of an unstable nuclei would eventually result into an atom achieving stability as either the excess proton or neutron is lost.

In terms of nuclear force, the force keeps the repulsion between similarly charged protons in an atom in balance. If an atom is stable, the nuclear force would keep the size of the nucleus from expanding excessively outwards.

In an unstable nucleus, the repulsion would be great and the nucleus would begin to expand outwards. This would result in growing size of the atom.
