What determines whether an atom is stable or unstable?
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.

Is 8 protons and 8 neutrons stable or unstable?
While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay.

What charge does 6 protons and 7 neutrons have?
Since the element is carbon, the atomic number (lower left) is 6, the mass number (upper left) is 13, and the overall charge (upper right) is 4+. This means that there are 6 protons, 7 neutrons (12 – 6) and 2 electrons (6 – 2 = 4) in this atom.

Does carbon have 6 protons and 7 neutrons?
For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes.
