Where I can find more about models of atom? I need a name of site for example….
Petar Mali said:Thomson's, Raderford's and Bor's atom models.
velocity_boy said:the Bohr model with its probability clouds is more accurate.
An atomic model is a representation or theory that describes the structure and behavior of an atom. It helps scientists understand the properties and interactions of atoms, which are the building blocks of matter.
The most widely accepted atomic model is the Bohr model, proposed by Niels Bohr in 1913. It suggests that electrons orbit the nucleus in specific energy levels, and that the number of electrons in the outermost energy level determines the chemical properties of an element.
Atomic models have changed significantly over time as new experimental evidence and technological advancements have been made. The earliest models, proposed by Democritus, suggested that atoms were indivisible and indestructible. Later models, such as the Thomson model and Rutherford model, introduced the idea of a nucleus and subatomic particles. Modern models, such as the quantum mechanical model, use complex mathematical equations to describe the behavior of electrons.
Atomic models help us understand the physical world by providing a framework for explaining the properties and behavior of matter. They allow us to predict and understand chemical reactions, the formation of molecules, and the behavior of materials at a microscopic level.
Yes, atomic models are constantly being refined and revised as new evidence is discovered. Scientific theories, including atomic models, are never considered to be 100% proven, but they can become widely accepted if they are able to explain and predict a wide range of phenomena and are supported by consistent evidence.
