20 de may. de 2024 · Learn about the basic building block of matter and chemistry, its subatomic particles, and its chemical properties. Explore the history of atomic theory and the latest discoveries about the atom's interior and interactions.
18 de may. de 2021 · Figure \(\PageIndex{1}\): The Structure of the Atom. Atoms have protons and neutrons in the center, making the nucleus, while the electrons orbit the nucleus. The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different.
Learn about the history and evolution of atomic structure, from Dalton's theory to Rutherford's model, and the discovery of subatomic particles such as protons, neutrons and electrons. Explore the concepts of isotopes, dual nature of matter and Bohr's atomic theory with examples and diagrams.

Learn about the history, models, and properties of atoms and their sub-atomic particles. Test your knowledge with quizzes, practice problems, and unit tests on topics such as isotopes, electromagnetic radiation, and quantum mechanics.
An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is ...
To understand why they are unique, you need to understand the structure of the atom (the fundamental, individual particle of an element) and the characteristics of its components. Atoms consist of electrons, protons, and neutrons.
