The Atom project

GOALS:
• To teach the other members of their group a sub concept of atomic structure.  
• Atomic number, Mass number, Isotopes, and Nuclear atom
• Learn how to use the periodic table as an effective teaching tool

• Professionally produced video lessons on Atomic Structure

TOPIC 2.1 THE NUCLEAR ATOM

  • Negatively charged electrons occupy the space outside the nucleus.
  • The mass spectrometer is used to determine the relative atomic mass of an element from its isotopic composition.
  • Atoms contain a positively charged dense nucleus composed of protons and neutrons (nucleons).

Topic 2.2 electron configuration

  • Emission spectra are produced when photons are emitted from atoms as excited electrons return to a lower energy level.
  • The line emission spectrum of hydrogen provides evidence for the existence of electrons in discrete energy levels, which converge at higher energies.
  • The main energy level or shell is given an integer number, n, and can hold a maximum number of electrons, 2n2.
  • A more detailed model of the atom describes the division of the main energy level into s, p, d and f sub-levels of successively higher energies.
  • Sub-levels contain a fixed number of orbitals, regions of space where there is a high probability of finding an electron.
  • Each orbital has a defined energy state for a given electronic configuration and chemical environment and can hold two electrons of opposite spin.
