Nucleon number and mass number are the same ie. the number of protons and neutrons in the nucleus. Atomic number is the number of protons only.Flavia said:What is differences between the definition of..
Nucleon number, atomic number, and mass number.
Is there any differences as i knew that those three symbol is A. am I right?
A nucleon is a subatomic particle that makes up the nucleus of an atom. It can be either a proton or a neutron.
Mass is defined as the total number of nucleons in an atom. It is measured in atomic mass units (amu).
Atomic number is the number of protons in the nucleus of an atom. It determines the element's identity and its placement on the periodic table.
Nucleon, mass, and atomic number are all related to the composition of an atom. The atomic number determines the number of protons, and the mass is determined by the number of nucleons (protons and neutrons) in the nucleus.
Atomic mass is the total mass of an atom, which includes the mass of all the protons, neutrons, and electrons. Atomic number is the number of protons in the nucleus of an atom.
