Oct 13 2016 nbsp 0183 32 This graphic takes a look at the key models proposed for the atom and how they changed over time Though our graphic starts in the 1800s the idea of atoms was around long before In fact we have to go all the way back to Ancient Greece to find its genesis Jan 17 2019 nbsp 0183 32 When scientific knowledge develops scientists learn more and their ideas about the atomic model change This is a story of how the atomic model gets changed when new evidence comes along Here is

A powerful model of the atom was developed by Erwin Schr 246 dinger in 1926 Schr 246 dinger combined the equations for the behavior of waves with the de Broglie equation to generate a mathematical model for the distribution of electrons in an atom Aug 15 2021 nbsp 0183 32 Throughout history the constitution of matter has had several models that have evolved until reaching the current atomic model Below is a timeline of the most important atomic models 1 Model of Democritus of Abdera 450 BC The Democritean atomic model was developed by the Greek philosopher Democritus of Abdera
Timeline of Atomic Models 8 gt 190 Bohr atomic model 1913 http en wikipedia wiki Niels Bohr In 1913 the Danish scientist Niels Bohr proposed a model where he placed each electron in a specific orbit energy level around the nucleus These orbits or energy levels are located at specific distances radius from the nucleus The atomic model consists of a nucleus containing protons and neutrons surrounded by electrons in shells The numbers of particles in an atom can be calculated from its atomic number and mass

John Dalton proposed the first modern atomic theory in 1803 J J Thomson discovered the electron in 1897 Ernest Rutherford s gold foil experiment in 1911 led to the discovery of the atomic nucleus Niels Bohr developed the planetary model of the atom in 1913 Atomic theory is the scientific theory of the nature of matter The theory states that matter is made up of small particles called atoms Prior to this theory matter was thought to be able to be divided into any small quantity The word atom is derived from the Greek atmos meaning indivisible
The atomic structure theory timeline traces the evolution of scientific understanding from Democritus concept of indivisible atoms to Bohr s model leading to our comprehension of subatomic particles and quantum mechanics Jan 11 2021 nbsp 0183 32 Atomic Theory Timeline 1937 Rutherford is known as the father of the nuclear age He decided to investigate atoms more closely by shooting small positively charged alpha particles at a sheet of gold foil Under Thomson s model the atom s thinly dispersed positive charge would not be enough to deflect the particles in any one place
