How many rings (energy levels) will an atom with 12 electrons have?

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

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.

Answer two atoms of oxygen;
