Atom Timeline

1704 Isaac Newton Proposed a mechanical earth with small unattackable cumulus in motion. 1803 John Dalton Proposed an nuclear theory with spherical material atoms based upon measurable properties of hoi polloi 1832 Michael Faraday study the do of electrical automobileity on solutions, coined term electrolysis as a dissever of molecules with electrical energy, developed laws of electrolysis. Faraday himself was non a proponent of atomism. 1859J. PluckerBuilt one of the initial gas discharge tubes (cathode re tube).1869Dmitri MendeleevArranged elements into 7 groups with akin(predicate) properties.  He detect that the properties of elements  were occasional(a) functions of the their atomic weights.  This became known as the semimonthly Law.1873James Clerk MaxwellProposed electric and magnetized field filled the void.1879Sir William CrookesDiscovered cathode rays had the avocation properties: travel in at once lines from the cathode; manage glass to fluoresce; impart a oppose charge to objects they strike; argon deflected by electric fields and magnets to suggest a prejudicial charge; cause pinwheels in their path to spin indicating they guard mass.1886E. GoldsteinUsed a cathode-ray tube to study transmission channel rays which had electrical and magnetised properties opposite of an electron.1894G.J.

StoneyProposed that electricity was make of discrete negative particles he called electrons . (Link to info on electrons)1895Wilhelm RoentgenUsing a cathode-ray tube he find that nearby chemicals glowed. promote experiments open up real penetrating rays orgasm from the CRT that were not deflected by a magnetic field. He named them X-rays.1896Henri BecquerelWhile studying the effect of x-rays on photographic film, he discovered some chemicals ad lib calve and give off very pentrating rays.1897J.J. ThomsonUsed a CRT to experimentally determine the charge to mass ratio (e/m) of an electron =1.759 x 10 8 coulombs/gram.1897J.J. ThomsonStudied canal rays and found they were associated with the proton H +...If you necessitate to get a sound essay, order it on our website: Ordercustompaper.com
