1
In what year was Democritus theory created?
1911
1897
5th or 4th century BC
2
What is the Democritus theoretical explanation?
The atom, an indivisible and eternal part, which remains in constant movement, is the primordial element, the principle of all things
An atomic model that incorporates quantized energy levels for the electrons around the nucleus. According to this model, electrons can occupy specific orbits around the nucleus, with each orbit corresponding to a certain energy level.
3
Who is the scientist behind the Democritus theory?
Democritus of Abdera, was a disciple and later successor of Leucippus of Miletus. His fame stems from the fact that he was the greatest exponent of the atomic theory or atomism.
Joseph John Thomson, a British physicist born in 1856. He is known for his discovery of the electron and for developing the model of the atom known as the "plum pudding model".
4
In what year was Dalton's theory created?
1803
1913
1925
5
What is the Dalton theoretical explanation?
matter is composed of indivisible and indestructible atoms, which combine in whole numerical proportions to form compounds
the wave equation that describes the behavior of subatomic particles, providing a means of calculating their physical properties and predicting probabilities of their location.

What is the Thomson theoretical explanation?
an atomic model in which most of the atom's mass and all of the positive charge are concentrated in a very small, dense nucleus, while the electrons rotate in orbits around that nucleus
atoms as consisting of a "soup" of positive charge in which electrons are scattered, comparable to plum pudding.
