Answer

Explanation:

Step1: Define nuclear chemistry

Nuclear chemistry studies the changes in the nucleus of atoms, including nuclear reactions, radioactivity, and properties of nuclei.

Step2: Identify nuclear particles and charges

Protons have a charge of +1, neutrons have a charge of 0. So in the nucleus, protons (+1 charge) and neutrons (0 charge) are present.

Step3: Determine destabilizing force

The electromagnetic repulsive force destabilizes the nucleus. Protons in the nucleus are positively - charged and repel each other due to the electromagnetic force.

Step4: Find force for stability

For the nucleus to be stable, the nuclear force must be stronger. The nuclear force is an attractive force that overcomes the electromagnetic repulsion between protons.

Step5: Define unstable nucleus

An unstable nucleus is one that spontaneously undergoes a nuclear change (radioactive decay) to become more stable.

Step6: Analyze nuclide stability

  • Bismuth - 209: Stable. It is the heaviest stable nuclide.
  • Lithium - 9: Unstable. It has an unfavorable neutron - to - proton ratio.
  • Oxygen - 16: Stable. It has a balanced neutron - to - proton ratio.
  • Technetium - 97: Unstable. All technetium isotopes are radioactive.
  • Vanadium - 51: Stable. It has a stable neutron - to - proton ratio.

Answer:

  1. The changes in the nucleus of atoms, including nuclear reactions, radioactivity, and properties of nuclei.
  2. Protons, +1; Neutrons, 0
  3. Electromagnetic repulsive force. Protons in the nucleus are positively - charged and repel each other due to this force.
  4. Nuclear force. It overcomes the electromagnetic repulsion between protons.
  5. A nucleus that spontaneously undergoes a nuclear change (radioactive decay) to become more stable.
  6. Bismuth - 209: Stable. It is the heaviest stable nuclide. Lithium - 9: Unstable. Unfavorable neutron - to - proton ratio. Oxygen - 16: Stable. Balanced neutron - to - proton ratio. Technetium - 97: Unstable. All technetium isotopes are radioactive. Vanadium - 51: Stable. Stable neutron - to - proton ratio.
