What happens when you split a hydrogen atom?

A hydrogen atom can be split into a proton and an electron. You need to put in an extra 13.6 volts of energy, but this disappears into the masses of the resulting particles. A proton can be split into three quarks, with a lot more energy. Quarks join up to nucleides, and these become atoms, giving off energy.

where is the circuit diagram ?

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
