The numbers of protons and neutrons in its nucleus, and the number of electrons in its valence shell. The number of protons and neutrons will affect the element and the isotope number, some isotopes are stable, some are not. Atoms are also more stable with a full outer energy level (octet rule - 8 electrons in the outermost shell).

What number in an atom determines what kind of atom it is?
The atomic number, which is the number of protons in the nucleus, determines what kind of atom it is.
What determines how an atom behaves when it encounters another atom?

What is the number of protons in one atom of an element determines the atom?
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
