Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom.
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 proposed that atoms have a dense, positively charged nucleus surrounded by negatively charged electrons orbiting the nucleus like planets around the sun. This led to the development of the planetary model of the atom.
Rutherford's model of the atom, known as the nuclear model, proposed that atoms have a small positively charged nucleus with electrons orbiting around it. This model revolutionized the understanding of atomic structure and laid the foundation for the development of quantum mechanics. It also led to further discoveries such as the existence of subatomic particles within the nucleus.
Rutherford discovered the proton in 1919 during his gold foil experiment. This experiment showed that atoms have a dense, positively charged nucleus at their center. Rutherford's findings revolutionized the understanding of atomic structure.
Ernest Rutherford published a paper proposing the planetary model in 1911. This followed the experiment performed by Hans Geiger and Ernest Marsden under the direction of Rutherford in 1909, where gold foil was bombarded with alpha particles .
The gold foil experiment supported the atomic model proposed by Ernest Rutherford, the Rutherford model. This model suggested that atoms have a small, dense nucleus at their center surrounded by a electron cloud. The experiment revealed that most of the atom's mass is concentrated in the nucleus and that the atom is mostly empty space.

Dalton's atomic model simply stated that all elements were made of tiny atoms, he said nothing about the structure of those atoms. Rutherford proposed that most of the mass of the atom is concentrated in a tiny central nucleus with positive charge.

The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.
Ernest Rutherford is known for discovering the nuclear structure of the atom, proposing that atoms have a small, positively charged nucleus surrounded by a cloud of negatively charged electrons. This model was a significant advancement in understanding the structure of atoms.

Rutherford proposed that atoms have a dense, positively charged nucleus surrounded by negatively charged electrons orbiting the nucleus like planets around the sun. This led to the development of the planetary model of the atom.
Ernest Rutherford is credited with developing the first model of the atom known as the Rutherford model in 1911. It proposed that atoms have a central nucleus surrounded by electrons in orbit. This model laid the foundation for our modern understanding of atomic structure.
Rutherford compared bombarding atoms with particles to playing with marbles because, just as marbles can bounce off each other or collide in unpredictable ways, particles striking atoms can lead to various outcomes, such as deflections or reactions, revealing the structure of the atom. During this phase of his work, Rutherford discovered the nucleus of the atom and identified the proton as a subatomic particle, fundamentally altering our understanding of atomic structure.
