An overview of the structure of an atom

Summary atoms are the building blocks of elements they are the smallest part of an element that react chemically atoms are divisible into still smaller particles called sub-atomic particles. Atomic structure the text provides a historical perspective of how the internal structure of the atom was discovered it is certainly one of the most important scientific discoveries of this century, and i recommend that you read through it. The bohr model has an atom consisting of a small, positively-charged nucleus orbited by negatively-charged electrons here's a closer look at the bohr model, which is sometimes called the rutherford-bohr model niels bohr proposed the bohr model of the atom in 1915 because the bohr model is a .

Learn about the structure of the atom, and how atoms make up matter an atom is the smallest unit of matter that retains all of the chemical properties of an element. A brief history of atoms we currently believe that the atom is the basic unit of matter which consists of a dense nucleus task – models of the structure of the atom. Summary: atomic structure atoms consist of protons and neutrons in the nucleus, surrounded by electrons that reside in orbitals orbitals are classified according to the four quantum numbers that represent any one particular orbital's energy, shape, orientation, and the spin of the occupying electron. Structure of the atom matter has mass and takes up space atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means.
