A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
Rutherford pictured the atom as a dense Nucleus surrounded by electrons.
a circle is there in which electrons that is electrons are revolving which are negatively charged and an atom is there in which minus sign is there.
The gold-foil experiment
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.

Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.

The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.
