Atomic models are theories developed by scientists that try to explain the functioning of matter and its phenomena. What are these theories based on?
Are based on the existence of the god particle
Are based on the existence of a fundamental particle, the nucleus.
Are based on the existence of a fundamental particle, the atom
2
The first atomic model, from 1808, which stated that the atom is a massive, indivisible and indestructible sphere, was proposed by:
J.J Tomson
Tesla
Thomas Edison
Dalton
3
In 1887, Thompson updated the atomic model stating the existence of:
-electric charge
valence shell
-proton charge
4
According to Rutherford's theory in 1911, the atom is formed by two regions:
Electron and nucleus
Core and stratosphere
Nucleus and electrosphere
5
Who proposed the existence of electronic layers in the electrosphere to resolve physical limitations in Rutherford's model in 1913?
Bohr
Schrodinger
Rutherford
6
In 1926, who determined the existence of orbitals, which are regions with different probability of finding an electron:
Thomson
Democritus
Dalton
Schrodinger
7
In the 5th century BC, in ancient Greece, philosophers used the term "atom" to refer to the small, indivisible and indestructible particles, which they believed to be the unit that constitutes matter:
Dalton e Chadwick
Rutherford e Bohr
Democritus e Leucipo

The current model of atomic structure is a combination of previous models, which describe the atom as a positive central nucleus surrounded by orbiting electrons in defined shells, each with a set of possible orbitals. The atomic structure is described by quantum mechanics and has wave behavior rather than corpuscular behavior.
