So, what are the four different models of the atom?
Although there were many models, four main ones have led to our current concept of the atom.
What is the name of the current model of an atom?
Schrodinger and Heisenberg Model. There is a key point about the Bohr model that is no longer accepted in current models of the atom. In the Bohr model, the electrons are still thought to orbit the nucleus just like planets orbit the sun. Actually, this is something that we can not say is true.
What is the first model of the atom?
Here is a timeline of some of the major ideas. Democritus was a Greek philosopher (470-380 B.C.) who is the father of modern atomic thought. He proposed that matter could NOT be divided into smaller pieces forever. John Dalton created the very first atomic theory.
