The number of protons is determining the element
The number of protons in an atom's nucleus determines its identity and is used to identify the element.
Neutrons are the particles that contribute to the mass of an atom, along with protons. Neutrons have a similar mass to protons, but they do not have a charge. The number of protons and neutrons in an atom's nucleus determines its atomic mass.
An atom is the smallest particle in matter with unique chemical properties. Each element is characterized by the number of protons in its nucleus, which determines its chemical behavior.
The number of protons in an atom determines which element it is (i.e Silver-47 protons vs. Gold-79 protons)
The particle of an atom that determines how it will bond with another atom is the electron, specifically the valence electrons. These are the electrons in the outermost shell of an atom and are responsible for chemical bonding. Atoms can share, gain, or lose valence electrons to achieve a stable electron configuration, leading to the formation of covalent, ionic, or metallic bonds.

The particle you are describing is an atom of iron. The number of protons in an atom determines its atomic number, which is 26 for iron. The sum of protons and neutrons gives the atomic mass number, which is 56 for this iron atom.
