The stability of an atom is determined by the:
Radioactivity is identified with radiation detection instruments.
The bonding properties of an atom are primarily determined by its valence electrons. Valence electrons are the outermost electrons in the atom's electron cloud and are responsible for forming chemical bonds with other atoms by either sharing, gaining, or losing electrons. The number of valence electrons an atom has influences its reactivity and ability to form different types of bonds.
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
The physical size of an atom is largely determined by the size of the electron cloud.
By the size of the atom and its mass
The atomic number of an atom is determined by the number of protons it has.
The number of protons in the nucleus of the atom.

yes it does
An atom's ability to chemically bond with another atom is described by its valence. Valence refers to the capacity of an atom to form bonds, determined by the number of electrons in its outermost shell. Atoms with unfilled valence shells tend to bond with other atoms to achieve stability, often following the octet rule.
By the atomic mass
Different isotopes of an atom are determined by the number of neutrons it contains.
