Why heavy nuclei are unstable?
Heavy, i.e. large, nuclei are unstable because their size is such that the attractive strong nuclear force starts to lose out over the repulsive effect of the electromagnetic interaction. The happens because the distance coefficient for the strong nuclear forces drops off more rapidly than does the electromagnetic interaction.
How are energy loss and nuclear stability related to radioactive decay?
The more unstable an atom the more likely it is to lose energy. The process atoms losing energy this way is called radioactive decay.
What causes something to be radioactive?
Atomic nuclei with more than 84 protons or a large neutron-to-proton ratio is unstable. These nuclei will lose alpha-particles (generally reduces the nucleus by 2 protons and 2 neutrons) or beta-particles (generally turns a neutron to a proton) until it becomes stable. This can take billions of years or a fraction of a second, depending on the isotope.
How does the petrol car lose energy to the surroundings?
Mostly in the combustion process.
What kind of ingredients can help water freeze?
Anything that would help the water lose energy. The freezing process is the process of the liquid losing energy and becoming a solid.
Some atoms such as carbon-14 whose nuclei are not stable lose parts of their nucleus through decay -In the process they become another element -Atoms such as this are said to be?
Radioactive.
What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
Does condensation lose or gain energy?
Condensation gives off energy. Matter is moving from the higher energy vapor state to a lower energy liquid state. This is an exothermic process.
Why does a power station lose a lot of energy during its generating process?
during the rotation of turbine its 65 percent energy is lost as heat
Is nuclear decay an example of a nuclear change?
Yes, it is. Nuclear decay is a process that an unstable atom goes through to lose energy and move toward a more stable state. (It may take more than one decay.) In nuclear decay, the nucleus undergoes a change by releasing a particle or particles and electromagnetic energy. Links are provided to related Wikipedia articles and related questions.
How do animals lose energy?
Animals lose energy simply by existing. The more strenuous the activity they are performing, the more energy they will lose.
How does a wind turbine lose energy?
wind turbines can not lose energy.
