Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

Who invented the periodic table? Dmitri Mendeleev invented the periodic in 1869‚ 5 years after John Newlands put forward his law of Octaves. Part of Dmitri’s periodic table He realised that the physical and chemical properties of elements were related to their atomic mass in a ’periodic’ way‚ and arranged them so that groups of elements with similar properties fell into vertical columns in his table. He also stated: The elements‚ if arranged according to their atomic mass‚ exhibit an apparent periodicity

There is a parlor game physics students play: Who was the greater genius? Galileo or Kepler? (Galileo) Maxwell or Bohr? (Maxwell‚ but it’s closer than you might think). Hawking or Heisenberg? (A no-brainer‚ whatever the best-seller lists might say. It’s Heisenberg). But there are two figures who are simply off the charts. Isaac Newton is one. The other is Albert Einstein. If pressed‚ physicists give Newton pride of place‚ but it is a photo finish -- and no one else is in the race. Newton’s claim
