Question

How am I able to calculate the amount of nucleons?

Answer 1

Hint :Nucleon is the collective term for protons and neutrons. Nucleons are the particles found within the nucleus of atoms. Most notably nucleons are a result of the strong interaction holding the atoms together which is stronger than the electrical force pushing them apart.

Complete Step By Step Answer:
The mass number is adequate to the entire number of nucleons (protons and neutrons) within the nucleus of an atom.
The total number of nucleons during a nucleus is typically denoted by the nucleon number A, where A = Z + N, Z protons and N neutrons. The chemical properties of an atom are determined by the amount of electrons, an equivalent because the number of protons Z. this is often called the number. Nuclei can have an equivalent number, but different numbers of neutrons. These nuclei are called isotopes, the Greek for "same place", since they're within the same place within the table.
 The separation energy per nucleon (proton or neutron) represents what proportion energy we might need to supply to tug the nucleus apart into separate free nucleons. The nuclear force tries to carry the nucleus together and thus increases the separation energy. The electrostatic force, which pushes the protons apart, decreases the separation energy.

Note :
Not only their masses but also their internal structures are almost identical. Because they're so similar, and since they're the particles out of which nuclei are made, protons and neutrons are often collectively called “nucleons”.
