The largest determinant to an atom's behavior is its electron configuration. An atom's electron configuration determines its interactions with other atoms, such as which atoms it can form bonds with and whether that bond is covalent or ionic. Additionally, the number of neutrons and protons influence the stability of the atom's nucleus.

The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom
The atomic number, which is the number of protons in the nucleus, determines what kind of atom it is.
The unique chemical properties of each element depend on the atomic number. The protein composition of a cell determines its shape, behavior, and function of the cell.
nass number is the number of neutrons plus protons in the nucleus of an atom
The electron configuration of an atom determines how it behaves when it comes into contact with another atom.
Neutron
An atom is the smallest part of an element that displays the chemical properties of that element. Each element is defined by the unique number of protons in its atom's nucleus, which determines its chemical behavior.
Electrons. The number of valence or "free" electrons an atom has determines how it can bond with other atoms.
the number of protons determines the atom.
Electrons are the subatomic particles found outside the center of the atom and are responsible for the chemical properties of the atom. Their arrangement in the electron cloud determines the reactivity, bonding, and other chemical behavior of the atom.
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.
