Answer:
I think is d.
Explanation:
particles that make up the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. the Instability of an atom's nucleus may result from an excess of either neutrons or protons.
I'm not sure, but hope it helps.
Forming very strong bond characteristics indicates that an atom is unstable. Hence, option D is correct.
An atom is any particle of matter which contains at least one proton.
An atom is unstable if the nucleus has an excess of internal energy.
The Instability of an atom's nucleus may be due to an excess of either neutrons or protons.
Hence, forming very strong bond characteristics indicates that an atom is unstable.
