What else can I help you with?
What is the current atom model?
A dense nucleus of protons and neutrons surrounded by electron clouds of different shapes and sizes.
Who were the scientists that were responsible for creating the atom model?
the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!
Who discovered the nuclear model?
Ernest Rutherford created the nuclear model of an atom!
How did Nagaoka contribute to the atomic theory?
He contriubuted to modern science with his model for atomic theory which he described was similar to the rings of saturn and he descibed that in his model of atomic theory. Hantaro Nagaoka was a great man and and he contributed alot of tings to modern science i cant name them all but he contributed alot of things to modern science
Describe a model for an external signal for growth?

When did Democritus discover his atomic model?
Democritus lived between approx. 460 bc and approx. 370 bc.
What leucippus and democritus experimental design used in their atomic model?
the deviced he use is just imaginary
Did Democritus say his model had electrons surrounding the nucleus at a distance?
No, Democritus did not propose the concept of electrons surrounding the nucleus at a distance. His atomic model was more focused on indivisible particles called atoms as the fundamental building blocks of matter. The idea of electrons orbiting the nucleus in specific energy levels was developed later by scientists like Niels Bohr.
What year was the atom proposed?
The first atomic model was proposed by the Greek philosopher Democritus in 442 BC.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
Explination of democritus model?
what year was the democritus model made?
How does the model describe the atom?
Today the accepted atomic model is quantic.
Who invented the atomic model?
The atomic model was developed by various scientists over time, with contributions from Niels Bohr, Ernest Rutherford, and John Dalton. However, the modern atomic model that we use today, with electrons existing in energy levels around a nucleus, was largely proposed by Niels Bohr in 1913.
What major changes occurred from Democritus's model to Thomson's model?
Democritus proposed the first atomic theory, suggesting that matter is made up of indivisible particles called atoms. Thomson's model, proposed in the late 19th century, introduced the idea of the atom as a sphere with embedded electrons, challenging the indivisibility of atoms seen in Democritus's model and suggesting the presence of subatomic particles. Thomson's model also laid the groundwork for the later development of the more accurate planetary model of the atom by Rutherford.
What is an appropriate model that has been developed to describe atomic structure?
The Bohr model is an appropriate model that has been developed to describe atomic structure. In this model, electrons orbit the nucleus in discrete energy levels or shells. It helps explain how atoms absorb and emit light energy.
What did democritus and Dalton and Thomson and Rutherford and bohr contribute?
Democritus proposed the concept of atoms as indivisible particles that make up all matter. Dalton developed the atomic theory, stating that elements are composed of indivisible atoms with specific properties. Thomson discovered the electron and proposed the "plum pudding" model of the atom. Rutherford conducted the gold foil experiment, leading to the discovery of the atomic nucleus. Bohr introduced the planetary model of the atom, with electrons orbiting the nucleus in specific energy levels.
Who made the mental model of the atom?
Democritus
