The Rutherford atom collapsed due to the instability of electrons orbiting the nucleus. According to classical physics, electrons in circular orbits should continuously emit radiation as they accelerate, leading to a loss of energy and a spiral inward toward the nucleus. This would result in the collapse of the atom, ultimately contradicting the observed stability of matter. This dilemma led to the development of quantum mechanics, which provided a new framework for understanding atomic structure.
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.

Rutherford discovered the atomic nucleus, proposed a nuclear model of the atom also he isolated nitrogen.
This was an idea of Ernest Rutherford (1871-1937) from 1911.

Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.
The gold-foil experiment
split the atom
In 1920, Rutherford gave the name proton to the positively charged particles in the nucleus of an 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 discovered in the early 1900s that most of an atom's mass is located in its nucleus.
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Rutherford pictured the atom as a miniature solar system, with a dense positively charged nucleus at the center and electrons orbiting around it in fixed paths. This model is known as the Rutherford model of the atom.
Ernest Rutherford is credited with the development of the "Rutherford Model" of the atom, which proposed that the atom consisted of a small, dense nucleus containing positively charged protons orbited by negatively charged electrons. This model was developed in 1911 based on experiments conducted in his laboratory.
