There is many places you come across nuclear energy! :)
Nuclear energy is released from the nucleus when U235 fissions, it appears initially as kinetic energy of the fission fragments, these are then stopped in the fuel material and turned to thermal energy. We can't use the nuclear energy directly.
Energy that is stored in the nucleus of an atom is called Atomic Energy or nuclear energy.
Nuclear energy
Energy (in the form of heat), also free neutrons.Binding energy
Nuclear Energy
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
Nuclear energy does not come from fossil fuels
nuclear energy
A toaster converts electrical energy into thermal energy. Some of that electrical energy may have come from a nuclear power plant.
Uranium
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
