It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)

How many nucleons are there in Carbon?

Any atom has only one nucleus in it. The difference is always in the number of nucleons. Nucleons are the fundamental particles of an atom that constitute the nucleus. Protons and neutrons are the primary nucleons. The number of protons is always different for different elements. For e.g., the number of protons in a carbon atom is 6


What is the difference between the atomic structure of the chlorine 35 and chlorine 37 isotopes?

A nucleus of the Cl-37 isotope contains two more neutrons than a nucleus of the Cl-35 isotope.


Particles is found in the nucleus of an atom?

Particles found in the nucleus of an atom are named as nucleons. There are mainly two type of nucleons. They are protons and neutrons. Protons are having positive charge but neutron is chargeless. To keep these nucleons together a particle known as pi mesons are exchanged between the nucleons.


Is the number of protons in the nucleus of an atom equal to the number of electrons in its outer rings?

Only for the isotope hydrogen-1. All other nuclei contain at least one neutron; the number of electrons present outside the nucleus is the same as the number of protons in the nucleus; and both protons and neutrons are nucleons. Therefore, in any nucleus except that of hydrogen-1, the number of nucleons in the nucleus is greater than the number of electrons outside the nucleus.


Strong nulear force?

It is the force between the nucleons within the nucleus. It is due to the exchange of mesons in between the nucleons. This force is a strange one and it has shortest range. It is some 1040 times greater than the gravitational attractive force between the nucleons.


What are nucleons in the nucleus?

Nucleons are particles are are included in the nucleus of an atom. These include neutrons and protons (and their anti-matter pairs).


Neutrons help hold the nucleus together?

The force between nucleons is called nuclear force.
