Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below.
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.

Gas will most likely  fill the container 

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
