Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom?

The experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom comes from the results of the Rutherford gold foil experiment. In this experiment, alpha particles were fired at a thin gold foil, and most particles passed straight through, indicating that the nucleus, where most of the atom's mass is concentrated, is very small compared to the overall size of the atom. This led to the development of the planetary model of the atom, where electrons orbit a small, dense nucleus.

What is the reason one can determine the number of electrons from the atomic number?

It is because atomic no. is decided on the basis of no. of protons in the atom and no. of protons is equal to no. of electrons in an atom.


Is electricity the flow of electrons?

Yes, electricity is the flow of electrons through a conductor. When electrons move in a uniform direction, it creates an electric current, which is the basis of how electricity works in circuits and powering devices.
