His experiment with the gold foil and the beam of positively charged particles proved that the nucleus of the atom is not solid. The beam past through the foil and bounced back. Rutherford's experiment contradicted Thomson's theory that an atom is solid.
Dalton's model of an atom, proposed in the early 19th century, viewed the atom as a solid, indivisible sphere. He believed that atoms of different elements had different masses and sizes, and that they combined in simple whole number ratios to form compounds. However, this model was later replaced by more advanced atomic models that better explained the behavior of atoms.
Protons and neutrons form the nucleusof the atom with electons orbiting it
Rutherford compared an atom to a solar system. But this would mean that as the electrons rotate they radiate energy and as they do so the radius of their path would keep on decreasing and would ultimately collide with the nucleus and the atom would be destroyed. but we know that this does not happen. Bohr on the other hand stated that the electrons rotate in specific orbits.
When energy is absorbed by an atom, the electrons in the atom can jump to higher energy levels. When they return to their original positions, they release the extra energy in the form of light. This is how light is produced in an atom.
On Bohr's model of the atom, electrons move in circular orbits around the nucleus. These orbits have specific energy levels, and electrons can transition between these orbits by either absorbing or emitting energy in the form of photons. The orbits were quantized, meaning that only certain orbits were allowed for the electrons to move in.
The atomic model of Rutherford was a step in the historical development of the today concept of an atom.

Niels Bohr is considered the founder of the modern atomic model.
it starts to break down into it's simplest form
Carbon with oxygen.
Electrons form a cloud around the nucleus of an atom. They have a negative charge and move rapidly in a probability distribution around the nucleus, representing the electron cloud or electron cloud model of an atom.
The atomic model in which electrons orbit the nucleus the way that planets orbit the sun is called the Bohr atom. We now know that atoms are really not very much like that at all, and electrons do not orbit the nucleus, they form shells, rather than orbits.
A Bohr model--Indicate all the electrons in the atom,in various shells in the atom. In the form of planetary model like nucleus is the center&electrons are surrounding it. A Lewis model--Indicate only the electrons in the outermost shell in the atom. In the form of electron dot structures we can write an atom in the middle & surrounding will be the valence electrons in the form of dot's.

The proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge equal in magnitude to that of the electron, thereby balancing the negatively charged electrons in the atom. Together with neutrons, which have no charge, protons form the nucleus of an atom.
The electron cloud form the electrically negative part of an atom; electrons are responsible for the chemical activity of elements.
