Niels Bohr is considered the founder of the modern atomic model.
The atomic model of Rutherford was a step in the historical development of the today concept 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.
Lavoisier made the atomic theory of matter, stating that matter is not destroyed or created, just changes form.
First of all he did'nt say that it was invisible, he said it was indivisible i.e. it cannot be divided further but it can be in the form of protons,electrons and neutrons.That's why it was not accepted. By the way he proposed atomic theory not a model. Models were proposed by THOMSON, RUTHERFORD and NEIL BOHR.
the wave mechanical model is the most current form of the atom. it is based on the probability of where electrons are going to be at a point in time. on diagrams it appears as a cloud around the nucleus.

The Bohr atom imagined that electrons orbit the nucleus in much the same way that planets orbit the sun. The modern atomic model has electrons in the form of a cloud that surrounds the nucleus without actually moving in orbit around it. Moving electrons would have to emit photons, lose energy, and spiral into the nucleus, thus destroying the atom. They don't really orbit.
Dalton never acknowledged the fact that the atomic structure consisted of protons nor electrons. Dalton's theory suggested:unlike Thomson who came up with the theory of the 'Plum Pudding Model', which consisted of a positive proton with electrons 'scattered' through it, like "...currants in a Christmas pudding..."hope this was somewhat helpful :)Matter is made up of indivisible atoms.All atoms of an element are identical.Atoms are neither created nor destroyed.Atoms of different elements have different weights and chemical properties.Atoms of different elements combine in simple whole numbers to form compounds.
Atomic atoms were the first to form.

The electron cloud form the electrically negative part of an atom; electrons are responsible for the chemical activity of elements.
