You can mainly blame the Russian chemist Dmitri Mendeleyev (or Mendeleev, or Mendeleyef - there are many different spellings of his name.)Back in the early 19th century, a German chemist named Johann Dobereiner noticed that some of the elements fitted naturally into groups of three, called triads, with similar chemical and physical properties. The English chemist John Newlands was the first to notice that if you arranged the elements in order of atomic mass, they seemed to have similar physical and chemical properties every eight elements. He called this the law of octaves, because the way in which these properties repeated every eight elements was similar to the way the same note was repeated every eight notes (octave) on a piano. However, at times his scheme broke down, and he realised there was something wrong with it, abandoning the octave idea. His fellow chemists mocked him for it - someone once said he'd have better luck listing the elements in alphabetical order and looking for patterns!It was Mendeleyev who in 1859 took Newlands' idea of looking for repeated properuties in the elements, and decided to create a table of elements in increasing atomic mass. Unlike Newlands, he left gaps where the pattern did not fit, and predicted new elements would be discovered, predicting their properties from the table. These elements were subsequently discovered, and since then, Mendeleyev's periodic table has been the most useful chart in chemistry.
he works with light lightness transparency..he lets light in through his roofs..he takes his functions outside to clear the interior...
Marie Curie used an invention called the electron.She also used a method that separated different elements in a substance made of 30 minerals called blende to find radium.
