Each element should be followed by the punctuation mark shown here. Earlier editions of the handbook included the place of publication and required different punctuation such as journal editions in parentheses and colons after issue numbers.
The periodic table was developed based upon the work of which scientist? 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 octavesbecause 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 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. Who was the greek doctor upon whose work modern medicine is based? His Code of Conduct for practicing medicin is still valued by the society of the medine science.Water and Dreams: An Essay on the Imagination of Matter (Bachelard Translation Series) 3rd Edition.
