What are the stable isotopes of carbon?

By far the most common isotope of carbon is carbon-12(12C), which contains six neutrons in addition to its six protons. The next heaviest carbon isotope, carbon-13 (13C), has seven neutrons. Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time.

12C and 13C are the most stable isotopes in carbon because they do not deteriorate into another form or element over time.
(The 12 and 13 are supposed to be small like an exponent, my keyboard lacks that function)

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
