  • Historical Development Of Atomic Structure

    1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element, but due to isotopes (caused buy nuclear varations)...

    The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge, surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus...

    The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism, however he didn’t write about his theories in detail. However, Democritus, his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that...

     The Development of the Atomic Theory Have you ever wondered how the atomic theory came to be? Or have you have wondered who it was that helped in its development? There was not just one man who came up with the atomic theory, but there were many scientists that contributed to its development. One of these scientists was Democritus, a Greek philosopher. Democritus was the son of Hegesistratus, and he was a student of Magians and Chaldaeans. By some authorities he was thought of as...

    The Atomic and Nuclear Structure of an Atom The atom has three main components the protons, neutrons, and electrons. The protons and neutrons make up the nucleus, while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge, and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative, positive or neutral. These are called...

  • The development of the theories into the structure of an atom

    Over time many theories have been developed into the structure of the atom and what the world around us is composed of. Many scientists and philosophers have dedicated their life works into trying to understand how atoms work and what they are made up of, although not all theories have been accepted they have all come together to form what we know today. It all started from a Greek scientist called Democritus, who developed the idea that everything is made up of smaller things, which he named atomos...

Located in the atom’s nucleus, protons and neutrons are referred to as nucleons. The electrons rest outside of the nucleus at various energy levels (orbitals). Most of an atom's mass comes from its very small nucleus, whose protons and neutrons each have a mass of approximately 1 u (atomic mass units). Electrons, on the other hand, have...
