An unstable force refers to a situation in physics where an object's equilibrium is sensitive to small changes in conditions, leading to a tendency to move away from its equilibrium position. This can occur in various contexts, such as in mechanical systems, where minor disturbances can cause significant changes in motion or position. In broader terms, an unstable force is often characterized by a lack of balance, resulting in unpredictable behavior or movement.
The stability of a nucleus is primarily determined by the balance between the strong nuclear force and the electrostatic repulsion among protons. A stable nucleus has a suitable ratio of neutrons to protons, which helps mitigate repulsion and enhances binding through the strong force. Unstable nuclei often have an excess of protons or neutrons, leading to imbalances that result in radioactive decay as they seek a more stable configuration. Factors such as energy levels and the presence of specific isotopes also contribute to nuclear stability or instability.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Unstable.
When the strong force is insufficient to hold unstable nuclei together, the nucleus may undergo radioactive decay. This process allows the nucleus to achieve a more stable configuration by emitting particles such as alpha particles, beta particles, or gamma rays. Over time, this decay leads to the transformation of the unstable nucleus into a more stable one, often involving the release of energy. Ultimately, this instability is a key factor in the life cycle of certain isotopes and their behavior in nuclear reactions.
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
When large unstable nuclei split because the electric for is greater than the nuclear force is nuclear decay.
The strong nuclear force doesn't balance the electrostatic force.

yes
A dipole is in unstable equilibrium in an electric field when the external electric field opposes the natural alignment of the dipole moment. This causes the dipole to experience a torque that rotates it away from its equilibrium position. If the force pushing the dipole away from equilibrium is stronger than any restoring forces, the equilibrium is considered unstable.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
