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.
On the contrary, the main force in the nucleus keeps particles together. This is called the strong nuclear force, and it keeps similarly charged protons together, overcoming the electrostatic repulsion that would push them apart. If there was a strong force pushing particles apart, elements could not exist except hydrogen! You may possibly be thinking of radioactive decay, for example beta particles being ejected. This is due to a proton losing mass and becoming a neutron, the loss of mass transforming to energy and the balance of charge giving a negative particle.
When large unstable nuclei split because the electric for is greater than the nuclear force is nuclear decay.
natural radioactivity
The strong nuclear force doesn't balance the electrostatic force.
Natural radioactivity.
strong force
no
Nuclear decay
it is called natural radioactivity
o Decreases as protons move farther apart
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.
