The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
NucleonsNucleons are subatomic particles, such as protons and neutrons, that exist in the nuclei (plural of nucleus) of atoms. Though a proton or neutron can exist outside the nucleus of an atom (though the neutron is unstable and will decay), either particle is considered a nucleon when we refer to them as the constituent parts of an atomic nucleus.Protons and neutrons reside in the NUCLEUS and are thus NUCLEONS. The probability of an electron being within a nucleus is quite small, so it is not considered a nucleon.
The number of protons in a nucleus of an atom is called the "proton number", strangely enough. If you are a physicist, you will most likely prefer this term. Chemists however, would rather call it "atomic number".
The term silver-96 indicates a mass number of 96 for that isotope of silver. The mass number of an isotope is the sum of protons and neutrons in the nuclei of its atoms. On the periodic table, the atomic number for silver is 47. The atomic number of an element is the number of protons in the nuclei of its atoms. The difference between the mass number and atomic number is the number of neutrons in the nuclei of the atoms of that isotope. In a neutral atom, the number of protons and electrons are equal. Therefore, silver-96 has 47 protons and 47 electrons in its atoms. The number of neutrons = 96 - 47 = 49.
"Used" is the wrong term to be used in this case. An atom is MADE up of protons,neutrons and electrons. Also, the number of protons or neutrons present in an atom depends on which atom is it or of which element it is.

Mass number is the total number of protons and neutrons. because the nucleus consists of protons and neutrons only, the sum of protons and neutrons is the total number of ALL the nucleons. note the term "ALL" here.. this is the reason why mass number is denoted as "A".
Atomic mass
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
Nucleon Number (total number of protons and neutrons)
Mankind refers to all human beings collectively. It is a term used to describe the human race as a whole.
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.

Atoms are the physical things that contain all these particles. The general term for all of them is Subatomic Particles.
